PURPOSE:To prevent a liquid product from generation even in case of exposure to a high temperature by using an insulating material obtained by mixing an inorganic filler with a given epoxy resin. CONSTITUTION:Insulation and fastening between armature coils 5, 5 and between armature coil 5 and armature core are performed by an insulating member 6. A material for the insulating member 6 to be used in this case is an insulating material obtained by heating a mixture combining 40% or more inorganic filler with epoxy resin of average molecular weight 700 or more containing a hardener and by processing said mixture into powders of 60 meshes or more after gelation and temporary hardening. Said insulating material is melted to adhere to necessary parts of a preheated armature and there after hardened by heating.
