Integrally molded body and method of producing same

An integrally molded body comprising:

• a board (A),
• a member (B), and
• an injection molded bonding resin (C) interposed between the board (A) whose one surface is a design surface and the member (B),
• wherein, inside the member (B), a first bonding section is disposed to space apart the board (A) and the member (B) and by which at least a partial region of an outer peripheral edge section of the board (A) bonds to the injection molded bonding resin (C),
• at least a part of the design surface-side surface of the integrally molded body has a region where the board (A), the member (B), and the injection molded bonding resin (C) are exposed, wherein 1) the board (A) has a member composed of at least one of a fiber reinforced resin member comprising reinforcing fibers and a thermosetting resin and a metal member, and 2) the board (A) has a sandwich structure sandwiching both surfaces of a core layer with skin layers each of which includes the member composed of at least one of a fiber reinforced resin member comprising reinforcing fibers and a thermosetting resin and a metal member, and the core layer is selected from a thermoplastic resin, a foam, and a porous base material comprising discontinuous fibers and a thermoplastic resin, the board (A) and the member (B) include a region overlapping via the injection molded bonding resin (C), and
• the overlapping region is formed by disposing the member (B) to overlap in parallel under the board (A) via the bonding resin (C),
• wherein a thermoplastic resin layer (D) is further provided on an outer surface of the board (A), and the board (A) and the injection molded bonding resin (C) are bonded via the thermoplastic resin layer (D).
