a terminal that is connected to the core wire at an end of the insulated electric wire; a first molded portion covering a portion at which the terminal and the core wire of the insulated electric wire are connected to each other; a second molded portion that is formed integrally with the first molded portion, that is softer than the first molded portion, and that protrudes from the first molded portion toward the side opposite to a terminal side while being in contact with an outer circumferential surface of the insulating coating; and a fixing member that has an annular shape surrounding the second molded portion, that is attached to the first molded portion and the second molded portion in a state in which the fixing member presses the second molded portion against the outer circumferential surface of the insulating coating, and that is a resin member that is harder than the second molded portion, wherein the fixing member is configured to be attached to the first molded portion and the second molded portion by one of axially sliding fit, radially press fit, tape winding fit, and heat-shrinking fit. ### Claim 2 (depends on 1) The molded portion-equipped electric wire according to claim 1, wherein the first molded portion is provided with a locking portion, the fixing member is provided with a locked portion that can be locked to the locking portion, and the fixing member is fixed to the first molded portion and the second molded portion in a direction in which the insulated electric wire extends, due to the locking portion and the locked portion engaging with each other. ### Claim 3 (depends on 2) The molded portion-equipped electric wire according to claim 2, wherein the second molded portion includes a first surface that faces the first molded portion and is in contact with an end surface of the first molded portion on the side opposite to the terminal side, and a second surface that faces away from the first molded portion, the fixing member includes a portion that is in contact with the second surface, and the fixing member is fixed due to the locking portion and the locked portion engaging with each other in a state in which the fixing member presses the second surface toward the first molded portion. ### Claim 4 (depends on 1) The molded portion-equipped electric wire according to claim 1, wherein the second molded portion includes a silicone resin. ### Claim 5 (depends on 1) The molded portion-equipped electric wire according to claim 1, wherein the insulating coating includes a silicone resin. ### Claim 6 (depends on 1) The molded portion-equipped electric wire according to claim 1, wherein the fixing member includes a plurality of fixing pieces and has the annular shape in a state in which the plurality of fixing pieces are assembled.
