In addition, the present invention provides a method for fixing a ceiling material for automobiles to a vehicle body, which has an adhesive force for a long period of time even under high temperature or low temperature conditions, is excellent in productivity, and does not cause a problem such as falling of a male-type engaging element even when a hot melt adhesive is used. A resin molded body with a hook-and-loop fastener, which is formed by integrating a non-foamed resin molded body and a male-type molded hook-and-loop fastener, wherein the male-type molded hook-and-loop fastener has at least a base plate, a plurality of male-type engaging elements rising from a front surface of the base plate, and a plurality of embedded elements rising from a back surface of the base plate, wherein a resin constituting the male-type molded hook-and-loop fastener is at least one selected from polyester elastomer and polyamide, and the resin molded body and the male-type molded hook-and-loop fastener are integrated by embedding at least a part of the embedded elements in the resin molded body. ## Claims ### Claim 1 A resin molded body with a hook-and-loop fastener, which is formed by integrating a non-foamed resin molded body and a male-type molded hook-and-loop fastener, wherein the male-type molded hook-and-loop fastener has at least a base plate, a plurality of male-type engaging elements rising from a front surface of the base plate, and a plurality of embedded elements rising from a back surface of the base plate, wherein a resin constituting the male-type molded hook-and-loop fastener is at least one selected from polyester elastomer and polyamide, and the resin molded body and the male-type molded hook-and-loop fastener are integrated by embedding at least a part of the embedded elements in the resin molded body, wherein a ridge portion continuous in a row direction is present on the base plate, and the male-type engaging element is formed on the ridge portion along the row direction, and wherein the thickness of the resin molded body is 1.0 to 50.0 mm, the base plate of the male-type molded hook-and-loop fastener being integrated with a substantially central portion of the resin molded body and having a smaller area than the resin molded body, arranged such that an edge portion of the resin molded body and an edge portion of the base plate of the male-type molded hook-and-loop fastener are never in contact with each other with a distance between the edge portions being 5-50 mm. ### Claim 2 (depends on 1) The resin molded body with a hook-and-loop fastener according to claim 1, wherein the male-type engaging element has a stem portion rising from the base plate and a protruding portion protruding from the stem portion, the protruding portion protrudes from a middle or a tip of the stem portion, and the tip of the protruding portion is inclined in a direction of the base plate. ### Claim 3 (depends on 1) The resin molded body with a hook-and-loop fastener according to claim 1, wherein the male-type engaging element is an engaging element that rises from the base plate, gradually tapers from a root to a tip without branching in the middle or at the tip portion, bends in the same direction as the row direction of the male-type engaging elements in the middle, and has a shape in which the tip approaches the surface of the base plate. ### Claim 4 (depends on 2) The resin molded body with a hook-and-loop fastener according to claim 2, wherein the male-type engaging element has plural protruding portions protruding from the stem portion, two or more of the protruding portions being provided in a vertical direction of the stem portion, and a total of four or more of the protruding portions being provided bilaterally symmetrically with respect to the stem portion. ### Claim 5 (depends on 1) The resin molded body with a hook-and-loop fastener according to claim 1, wherein the male-type molded hook-and-loop fastener and the resin molded body have different color tones. ### Claim 6 (depends on 1) The resin-molded body with a hook-and-loop fastener according to claim 1, wherein the base plate has a thickness of 0.10 to 0.40 mm, and a height of the male-type engaging element from the base plate surface is 1.5 to 4.0 mm. ### Claim 7 (depends on 2) The resin molded body with a hook-and-loop fastener according to claim 2, wherein a ratio of an interval (mm) between the stem portions to a thickness (mm) of the stem portions is 0.30 to 0.80 times when a row direction of the male-type engaging elements is used as a reference. ### Claim 8 (depends on 1) The resin molded body with a hook-and-loop fastener according to claim 1, wherein the distance between the edge portions is 8 to 20 mm. ### Claim 9 (depends on 1) The resin molded body with a hook-and-loop fastener according to claim 1, wherein the base plate, the male-type engaging element, and the embedded element are formed of the same resin composition, and the base plate is composed of a single layer. ### Claim 10 (depends on 1) A method for producing the resin molded body with a hook-and-loop fastener according to claim 1, the method comprising the steps of: inserting the male-type molded hook-and-loop fastener into a male-type molded hook-and-loop fastener accommodating concave portion in a die; and injecting a non-foamable resin liquid into the die to integrate the male-type molded hook-and-loop fastener and the resin molded body. ### Claim 11 (depends on 10) The method for producing a resin molded body with a hook-and-loop fastener according to claim 10, wherein a die having a male-type engaging element accommodating concave portion in the male-type molded hook-and-loop fastener accommodating concave portion is used. ### Claim 12 (depends on 1) A method for fixing a ceiling material for automobiles to a vehicle body, the method comprising: attaching the resin molded body with a hook-and-loop fastener according to claim 1 to a back surface of the ceiling material for automobiles by any one of a method of attaching using an attaching tool and a method of attaching by adhesion using a hot melt resin; and then engaging a female-type hook-and-loop fastener attached to a vehicle body main body with a male-type molded hook-and-loop fastener of the resin molded body with a hook-and-loop fastener. ### Claim 13 (depends on 1) The resin molded body with a hook-and-loop fastener according to claim 1, wherein the back surface of the base plate comprises at least two adjacent rows of male-type engaging elements, with a row of embedded elements present parallel to a row of said male-type engaging elements.
