| abstract |
The present invention is an insulating tape including: a mica layer containing mica; a reinforcing layer that is laminated onto the mica layer and contains a filler and a fibrous reinforcing material; and a flat sheet layer that is laminated onto the reinforcing layer and contains flat sheet-shaped inorganic particles having an aspect ratio of at least 30. In this insulating tape, the filler is supported in advance, and does not therefore flow out during manufacture of a stator coil (during hot-pressing in particular). As a result, an insulating coating exhibiting high thermal conductivity can be formed. |
