Abstract
Provided is a resin composition configured to show a small change in the void ratio of hollow resin particles during mold processing and configured to stably mold a lightweight molded product. The resin composition is a resin composition comprising 50 parts by mass to 95 parts by mass of a thermoplastic plastomer and 5 parts by mass to 50 parts by mass of hollow resin particles, wherein the hollow resin particles have a void ratio of from 50% to 85%; wherein the hollow resin particles have a shell containing a resin; and wherein, with respect to 100 parts by mass of repeating units constituting the resin, 30 parts by mass to 100 parts by mass of a crosslinkable monomer unit and 0 part by mass to 70 parts by mass of a non-crosslinkable monomer unit are contained as a polymerizable monomer unit.
