Abstract of the Disclosure Disclosed herein is an internal combustion engine piston comprising a piston cap constituted by plural ceramic pieces, and a metal piston body, the piston cap being fixed to the top portion of the metal piston body, wherein the piston cap is made of one or more kinds of ceramic materials, and the ceramic pieces constituting the ceramic cap and the metal piston body are bonded together through a metallized layer coated onto the ceramic pieces and a metal-plated layer coated onto the metallized layer in such a manner that the bonding area between the ceramic piece or pieces and the metal piston body may be larger at the top central portion of the metal piston body than that between the ceramic piece or pieces and the metal piston body at the other portion. Disclosed is also a method of producing the same, which comprises forming the piston cap from one or more kinds of ceramic materials, coating the surface of at least one ceramic piece which is to be faced with and bonded to the piston body with a metallized layer, coating the surface of the metallized layer with a metal plated layer, arranging the ceramic pieces in a depression formed at the top portion of the metal piston body, and bonding the piston cap and the metal piston body together through the metallized layer and the metal plated layer such that the bonding area between the ceramic piece or pieces and the metal piston body may be larger at the central top portion than at the other portion.
