PROBLEM TO BE SOLVED: To obtain higher adhesive strength in a resin molding sealing an insert component with a synthetic resin.SOLUTION: In a resin molding, a synthetic resin member 20 sealing an insert component 10 having a functional group is formed by adding an adhesive component 20b which adheres to the functional group of the insert component composed of a thermosetting resin or the like to a thermoplastic resin becoming a base polymer 20a; and further, has a structure where adhesive component molecules of required number are dispersed into a continuous phase for obtaining the adhesive strength with the insert component, in a continuous phase and a condensed phase composed of the base polymer and the adhesive component. The functional group of the adhesive component added to the synthetic resin member is chemically reacted with the functional group present at the surface of the insert component to obtain higher adhesive strength. Also provided is a method for confirmation where various conditional setting upon second molding is performed so as to satisfy the conditions, molecular simulation is performed, and, based on this, whether desired adhesive strength can be obtained or not with a synthetic resin member is confirmed.SELECTED DRAWING: Figure 1 |
