[0030] (stator)
[0031] figure 1 It is an external perspective view of the stator 1. The stator 1 includes a stator core 2 and a coil 3 . It should be noted that, in figure 1 In , part of the coil 3 is omitted for explanation.
[0032] The stator core 2 is formed in an annular shape with the axis C as the center. Teeth 21 are formed on the inner peripheral surface of the stator core 2 . The teeth 21 protrude radially inward from the inner peripheral surface of the stator core 2 . A plurality of teeth 21 are provided in the circumferential direction.
[0033] Slots 22 are formed between the teeth 21 , and coils 3 described later are inserted into the slots 22 . A rotor (not shown) is rotatably arranged inside the stator core 2 around the axis C. As shown in FIG.
[0034] In the following description, the direction along the axis C of the stator core 2 may be referred to as the axial direction, the direction perpendicular to the axis C may be referred to as the radial...

[0070] Next, a second embodiment of the present invention will be described. Figure 6 is a cross-sectional view of the electric wire 10 of the second embodiment, and is the same as figure 2 The III-III line corresponds to the sectional view. This embodiment differs from the above-described embodiments in that the porous layer 51 has a single layer of the porous layer-forming film 61 . In the following description, the same reference numerals are assigned to the same configurations as those of the above-mentioned first embodiment, and description thereof will be appropriately omitted.
[0071] In this embodiment, the porous layer 51 has a single porous layer forming film 61 . The non-voided layer 52 has a non-voided layer-forming film 62 . The void layers 51 and the non-void layers 52 are alternately arranged in the radial direction of the conductor 4 . In other words, the void layer forming films 61 and the non-void layer forming films 62 are alternately arranged in one ...
