Insulation composition and an insulating sheet containing it

PROBLEM TO BE SOLVED: To provide an insulating composition which is comparatively easily handled upon molding and has high adhesiveness to a metal such as copper and high heat conductivity. SOLUTION: The insulating composition is a mixture of a liquid crystalline polymer and a thermosetting resin, a liquid crystalline polymer phase formed of the liquid crystalline polymer and a thermosetting resin phase formed of the thermosetting resin are separated and the liquid crystalline polymer phase forms a continuous phase. The liquid crystalline polymer preferably includes a liquid crystal skeleton of phenyl benzoate, biphenyl, stilbene, diazobenzene, benzylidene aniline or the like and the thermosetting resin is preferably an epoxy resin.
