Integrally molded body

In order to solve reduction in strength and rigidity at a weldline which is a problem of an injection molding body, and enable free design such as thin wall molding or complex shape molding of the injection molding body, there is provided an integrally molded body in which a substrate for reinforcement (a) having a discontinuous fiber (a1) and a resin (a2) and an injection molding body (b) having a discontinuous fiber (b1) and a resin (b2) are integrated, in which the substrate for reinforcement (a) has a difference in an orientation angle of the discontinuous fiber (a1) in each of regions obtained by dividing a major axis direction of the substrate for reinforcement (a) into 10 equal parts of within 10&#xb0;, and the substrate for reinforcement (a) covers a part or all of a weldline of the injection molding body (b) to be integrated with the injection molding body (b).
