Abstract

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, for example during hot-pressing. As a result, an insulating coating exhibiting high thermal conductivity can be formed.
