Abstract
The slot liner (13) includes a laminated insulation sheet (131) having a length (L1) longer than a length (L2) of a stator core in an axial direction and a pair of reinforcing sheets (135, 136). The laminated insulation sheet includes an outer insulation sheet (134) in contact with an inner surface (112d) of the slot and an inner insulation sheet (132) in contact with a conductor. Each of reinforcing sheets is folded back in the axial direction in such a way as to cover an end surface (134a, 134b) of the outer insulation sheet and includes a folded portion (135e, 136e) that covers the end surface of the outer insulation sheet, a first end portion (135f1, 136f1) disposed between the inner surface of the slot and the outer insulation sheet, and a second end portion (135g, 136g) disposed between the outer and inner insulation sheets.
