1. A swash plate compressor, comprising: a swash plate which rotates around a rotary shaft; a piston which moves forward and backward in response to the rotation of the swash plate and in which a hemispherical concave sliding surface is formed; and a shoe in which there are formed a flat end surface portion which comes into sliding contact with the swash plate and a spherical surface portion which comes into sliding contact with the sliding surface of the piston, wherein a columnar portion is formed between the spherical surface portion and the end surface portion in the shoe, and in a boundary area between the columnar portion and the spherical surface portion, there is formed a spherical-surface-portion side flange which protrudes radially outward and constitutes the spherical surface portion and an outer circumferential surface of the columnar portion is such that an intermediate area between the spherical surface portion and the end surface portion is formed as a swollen portion which swells radially outward.
