An internal combustion engine for enhancing a heat radiation property of combustion gas, can sufficiently secure strength thereof relative to combustion gas, and a weight reduction thereof can be realized. A piston for an internal combustion engine is constituted of a head part, a cylindrical skirt part extending from a lower part of the head part. A pair of pin boss parts are formed on both opposing side walls to each other of the skirt part. A plurality of recessed parts, the cross sections thereof being presented as smooth circular arcs, are formed on a surface on an opposing side to a surface facing to a combustion chamber of the head part, that is, to a reverse face.
