Abstract
A mica tape formed by a paper-making process from a mixture of the mica particles and at least one selected from the group consisting of a short fiber made of a nitrogen-free organic material and a short fiber made of an inorganic material, and an insulated coil by winding the mica tape around a conductive coil and impregnating the mica tape with a solventless thermo-setting resin.
