Abstract
PURPOSE: To increase heat discharge of coil by providing cooling duct between coils.
CONSTITUTION: Bottomed cylindrical metal die 7 is provided with glass bead 9 and plastic film 10 to form duct member 14. Duct member 14 is installed on the coil conductor 12 wound around the winding pattern by the designated number of turns. Additional coil conductot 13 is wound around it to form the coil. The coil thus formed is set in the molding metal die. Molding resin 15 is injected and the molding die is removed after heating and herdening of resin. Cooling duct is formed by drawing the duct member 14.
