Abstract
(EN)
Provided are a molded body and a method for manufacturing a molded body, the molded body comprising: reinforced fibers having a weight average fiber length of 1 mm or more and 100 mm or less; and a thermoplastic resin, wherein the molded body is provided with a first main shape surface part, a second main shape surface part connected to the first main shape surface part in a crossing state, and a connection surface part connected to both the first main shape surface part and the second main shape surface part, the connection surface part protrudes from the first main shape surface part and the second main shape surface part on a valley side formed by the first main shape surface part and the second main shape surface part, and reinforced fibers are continuously dispersed in an in-plane direction at a boundary region between the first main shape surface part and the connection surface part and a boundary region between the second main shape surface part and the connection surface part.
