PROBLEM TO BE SOLVED: To provide a structure in which, in a resin molded body in which an insert and a thermoplastic resin are joined, concentration of vacuum voids in the vicinity of the joining interface therebetween is suppressed and a method for manufacturing the same.;SOLUTION: In a resin molded body comprising a first member 10 as an insert and a thermoplastic resin 20 as a second member covering a part of the first member 10, the first member 10 is provided with a void suppression portion 11 that covers a joint portion 10c joining to the thermoplastic resin 20 of the first member 10. As a result, the thickness of the thermoplastic resin 20 in the vicinity of the joint portion 10c is reduced, so that the concentration of the negative pressure due to cooling and solidification, and contraction of the thermoplastic resin 20 is suppressed in the vicinity, and the concentration of the vacuum voids in the joining interface between the first member 10 and the thermoplastic resin 20 is suppressed.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
