A method of producing a piston for a swash plate type compressor including a head portion (70) which is slidably fitted in a cylinder bore (12) of the compressor, and an engaging section (70) which engages a swash plate (60) of the compressor, wherein a blank including a hollow cylindrical head section (168) corresponding to the head portion and an engaging section (165) corresponding to the engaging portion is formed by a pore-free die-casting method, such that the head section and the engaging section are formed integrally with each other at the closed end by the head section, and wherein a closing member (164) is fixed to the hollow cylindrical head section so as to close its open end, for thereby providing the head portion of the piston.
