(57) [Summary] [PROBLEMS] To prevent a decrease in electrical characteristics and a decrease in mechanical strength as much as possible. The resin molded product 1 After adding a small amount of a curing agent (peroxide) to the maleic unsaturated polyester resin, an inorganic filler composed of powdered calcium carbonate and aluminum hydroxide, a release agent composed of a fat or oil salt such as zinc stearate, It is composed of an unsaturated polyester resin premix (hereinafter, premix) kneaded into a putty by adding a colorant, mixing well, and finally adding microcapsules and glass fibers by a kneader. The microcapsule 2 includes first and second microcapsules 3 and 4 as a core component. The first microcapsules 3 include a main component 5 of an epoxy resin as a core component, and the second microcapsules 4 include a curing agent 6 for an epoxy resin as a core component. |
