A piston (13) for an internal combustion engine includes a crown part (50), a land part (61) extending from the crown part (50), a skirt part (97) adjoining the land part (61), and a linking boss (54) protruding from a reverse surface (53) of the crown part (50) and forming a spherical joint (14) with a small end (24) of a connecting rod (16). The piston (13) is divided into an upper piston part (51) having the land part (61), and a lower piston part (58) having the skirt part (97) and a plurality of molded plate members (111, 112) formed by press-molding plates.
