The tip seal 40 has a shape in which the height position in the direction of extension of the coil central axis X2 changes continuously from one end W1 to the other end W2 in the coil extension direction. If an external load is applied in the direction of extension of the coil central axis X2, the tip seal 40 extends in the direction of extension of the coil central axis X2. The tip seal 40 is formed in such a manner that in a state of being fitted inside the tip seal groups 2c, 3c and without external force being applied, the tip seal bottom surface 40b that faces the bottom surfaces 2d, 3d of the tip seal grooves 2c, 3c is positioned inside the tip seal grooves 2c, 3c over the entirety from one end W1 to the other end W2 in the direction of extension of the coil.
