Integrally molded body and method for producing the same

A method for producing an integrally molded body comprising arranging a substrate for reinforcement (a) having a discontinuous fiber (a1) and a resin (a2) in a mold and integrating the substrate for reinforcement (a) with a weldline of an injection molding body (b) having a discontinuous fiber (b1) and a resin (b2),

• the substrate for reinforcement (a) having a difference in an orientation angle of the discontinuous fiber (a1) in each of regions obtained by dividing a length direction of the substrate for reinforcement (a) when arranged in the mold into 10 equal parts of within 10° ,
• wherein the substrate for reinforcement (a) has a thickness of 0.03 mm or more and 0.25 mm or less, and
• wherein the substrate for reinforcement (a) is 5% or more and 30% or less with respect to projected area of the integrally molded body.

• the substrate for reinforcement (a) having a difference in an orientation angle of the discontinuous fiber (a1) in each of regions obtained by dividing a length direction of the substrate for reinforcement (a) when laying up the substrate for reinforcement (a) on the injection molding body (b) into 10 equal parts of within 10° ,
• wherein the substrate for reinforcement (a) has a thickness of 0.03 mm or more and 0.25 mm or less, and
• wherein the substrate for reinforcement (a) is 5% or more and 30% or less with respect to projected area of the integrally molded body.
