An object of the present invention is to provide an insulation sheet having high thermal conductivity in the in-plane direction. The present invention provides an insulation sheet comprising insulating particles and a binder resin, wherein, for the entire cross-section of the sheet perpendicular to the in-plane direction, the insulation sheet contains 75 to 97% by area of the insulating particles, 3 to 25% by area of the binder resin, and 10% by area or less of the voids.

The present invention belongs to the field of thermal functional devices. Provided is a topological insulation device having negative thermal expansion. In the topological insulation device, three assemblies of different properties are constructed using assembly units of special geometric structures, and then different assemblies are assembled to form an outer heat-conduction ring and a thermal insulation region, which is wrapped by the outer heat-conduction ring, so that the device has the characteristics of surface thermal conduction and internal thermal insulation, and an edge state and a topological protection property, which are similar to those of an electrical topological insulator, are realized in a macroscopic heat conduction process.

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.
