1. An integrally molded body having a rectangular planar structure comprising: a plate material (A) having a surface of a design side; an outer resin material (C1) containing a thermoplastic resin and; an inner resin material (B1) containing a thermoplastic resin interposed between the plate material (A) and the outer resin material (C1),
the rectangular planar structure having: a first junction to join the inner resin material (B1) with a whole region or a partial region of an outer peripheral side face and/or an outer peripheral edge of the plate material (A); and a second junction to join the outer resin material (C1) with a whole region or a partial region of an outer peripheral side face and/or an outer peripheral edge of the inner resin material (B1), wherein
one or more weld lines are formed on the inner resin material (B1) and the outer resin material (C1) on a non-design side opposite the design side of the plate material (A), and a first weld line (B2) formed on the inner resin material (B1) is located at a position shifted from that of a second weld line (C2) formed on the outer resin material (C1) closest to the first weld line (B2) in a direction parallel to an outer peripheral side of the integrally molded body.
