Zusammenfassung:	PURPOSE:To provide a sealed type motor-driven compressor having a long life even when an ordinary polyethylene terephthalate insulating film of a low molecular weight is employed, in the sealed type motor-driven compressor. CONSTITUTION:The life of a sealed type motor-driven compressor, which is same or longer than the same compressor employed stably in present market, can be retained by a method wherein polyethylene terephthalate, having average molecular weight of 15000 or less, is coexisted.
