Abstract
A molded product includes a matrix formed of a polymer material and a plurality of capsules dispersed in the matrix. An unevenness is formed on a surface due to expansion of the capsules. Some of the capsules have expanded without bursting and include an exposed outer shell portion that protrudes from a surface, and/or some of the capsules have burst and include an outer shell protruding portion that protrudes outward from the surface. Finish processing is performed, which eliminates the outer shell protruding portions and/or the exposed outer shell portions from the surface. This results in a molded product in which a color difference due to frequency of contacting an object, etc. is not easily generated.
