PROBLEM TO BE SOLVED: To enable simple and easy withdrawal of winding parts by providing an insulating coil case consisting of a winding container that accommodates cylindrical winding formed inside of an insulating object and at one of its ends and an opening connected to the winding container, and by accommodating the cylindrical winding in the winding container. SOLUTION: In a coil for electric equipment, an insulating coil case 1 is constituted by an insulating object 3 with an empty part 2 in its inside and having a winding container 5 for accommodating cylindrical winding 4 formed inside and at one of the ends of the insulating object 3, and an opening 6 connected to the winding container 5. The cylindrical winding 4 is formed by alternately winding an enameled copper conductor 4B and an interlayer insulator 4C on an inner peripheral insulating object 4A made of glass-fiber-reinforced epoxy resin. The cylindrical winding 4 is assembled in the winding container 5, and extending wires 6A and 6B of the cylindrical winding 4 are connected to metal fixtures 1A and 1B for connecting terminals, respectively, to complete the coil 8 for electric equipment. In case of scrapping, the insulating coil 1 and the cylindrical winding 4 can be disjoined simply from the coil 8 for electric equipment.
