Molded body and method for manufacturing same

A molded body comprising a reinforced layer including stacked fiber reinforced resin layers, each of the fiber reinforced resin layers including a set of a plurality of reinforcing fibers oriented and arranged in one direction and a matrix resin impregnated in the plurality of the reinforcing fibers, wherein

• the reinforced layer is composed only of a plurality of thin-film shaped fiber reinforced resin including a plurality of reinforcing fibers oriented and arranged in one direction and a matrix resin impregnated in the reinforcing fibers, that are fused with each other, thereby each of the thin-film shaped fiber reinforced resin forming each layer of the stacked fiber reinforced resin layers,
• the reinforced layer includes a matrix resin rich region between adjacent sets of a plurality of the reinforcing fibers that are continuously placed in a lamination direction, each set of the adjacent plurality of the reinforcing fibers being contained in two adjacent fiber-reinforced resin layers that are continuously disposed in a lamination direction,
• the reinforced layer includes a plurality of orientation shifted layers, the orientation shifted layers being at least a part of the fiber reinforced resin layers arranged with a shifted angle of 25 degrees to 65 degrees or −65 degrees to −25 degrees, the shifted angle being an angle of the plurality of the reinforcing fibers with respect to a longitudinal axial direction of the reinforced layer,
• the plurality of the orientation shifted layers includes a positive orientation shifted layer where the shifted angle is 25 degrees to 65 degrees;
• and a negative orientation shifted layer where the shifted angle is −65 degrees to −25 degrees,
• the plurality of the orientation shifted layers includes a pair of the orientation shifted layers continuously disposed in a lamination direction, and
• the molded body does not include a non-orientation shifted layer adjacent to an orientation shifted layer among the plurality of the orientation shifted layers, the non-orientation shifted layer being a layer including a plurality of the reinforcing fibers arranged in an orientation of an angle greater than −25 degrees and smaller than 25 degrees, with respect to the longitudinal axial direction of the reinforced layer, and the matrix resin impregnated in the plurality of the reinforcing fibers and fused with the matrix resin of the orientation shifted layer.
