Mica has excellent insulating properties and is a typical insulating material. The volume resistivity of mica is extremely high, especially in the direction perpendicular to the perfect cleavage surface of the mica. Thanks to its laminar structure, mica has a very high surface resistance. Compared to other insulating materials, the tangent of dielectric loss angle of mica is very small and the dielectric loss is low.
