摘要

The present invention provides a mica tape, comprising a mica foil (12), a glass cloth (14), and an inorganic filler (16) arranged on the glass cloth, wherein the mica tape is wound a plurality of times about an outer circumferential surface of a conductor portion of an electrical rotating machine coil so as to form an insulating layer for the coil, and the inorganic filler (16) has a Mohs hardness falling within a range of 1 to 7 and exhibits a heat conductivity superior to those of the mica foil (12) and the glass cloth (14). According to the present invention, the inorganic filler is excellent in the heat conductivity and has a Mohs hardness not lower than that of the glass cloth contained in the mica tape, when used together with the inorganic filler, whereby, even if the mica tape is wound about the conductor portion while applying a prescribed tension to the mica tape, the mica tape is not broken, and it is possible to form an insulating layer capable of exhibiting the highest heat conductivity owned by the inorganic filler.
