Abstract

PURPOSE: To increase reliability of coil through prevention of cracking in the layer of insulating resin by providing vacant space between element coil and insulating resin layer.
CONSTITUTION: On the surface of element coil 11 made by winding insulator-coated electric wire round is provided a separating-type film, which is put in a metal mold and the like and impregnated with resin so as to form insulating resin layer 12, and then vacant space 15 is provided between the coil and the layer. Furthermore, in case there is large potential difference between element coil 11 and voltage to ground, semiconductive layers 16 and 16' are provided on both sides of vacant space 15 to prevent the generation of electric discharge. In this way, because vacant space 15 allows insulating resin layer 12 to make free expansion and contraction so as to reduce internal stress, it becomes possible to prevent cracking due to thermal shock and the like and increase reliability of coil.
