Zusammenfassung:	To provide a segment seal configured so that an error in attachment of a pair of seal rings in a tandem segment seal can be prevented.The segment seal 1 is configured to seal an annular clearance between a housing 2 and a rotary shaft 3 in a state in which a pair of seal rings 10A, 10B are attached in an unrotatable state between one end portion 20 of the housing 2 and a support member 40 attached to the housing 2 so as to be opposite to the one end portion in an axial direction. The segment seal 1 includes an anti-rotation member 30 placed not to rotate relative to the housing 2 or the support member 40, provided with a pair of raised portions 32A, 32B fitted to the pair of seal rings 10A, 10B to prevent rotation of the pair of seal rings 10A, 10B, and configured such that at least one of the raised portions 32A, 32B has a shape fittable only to either one of the seal rings 10A, 10B.
