PROBLEM TO BE SOLVED: To provide an insulator which is capable of improving a degree of freedom in assembly work of a stator and can be firmly fixed to a stator core.SOLUTION: The insulator includes a main body part 31 and a foamable adhesive sheet 36. The main body part 31 includes a flange 34 that is disposed between a yoke and a coil, and a cylindrical part 32 into which teeth are inserted, and is formed from an insulation resin. The foamable adhesive sheet 36 is brought into contact with both a radial inner side face of the yoke and a circumferential side face of the teeth while including a corner where the radial inner side face of the yoke and the circumferential side face of the teeth are connected, and fixed to the main body part 31 and has a foamable property by which the foamable adhesive sheet is foamed by heating, and adhesiveness.SELECTED DRAWING: Figure 7 |
