A single-headed piston type swash plate compressor provided with:

• a housing internally defining and forming cylinder bores, a crank chamber, a compression chamber, a suction chamber, and a discharge chamber;
• a single-headed piston accommodated in each of the cylinder bores to be able to reciprocate therein and to define the compression chamber therein;
• a drive shaft driven by an external drive source and supported by the housing;
• a swash plate synchronously rotatably supported with respect to the drive shaft;
• and
• a pair of shoes provided at the front and rear of the swash plate so as to be accommodated in the piston and to drive the piston;
• wherein
• the swash plate is comprised of a swash plate substrate made of a first metal and a coating formed on a rear surface of the swash plate substrate for improving the slidability with the first metal;
