Abstract
A method of manufacturing a coil unit includes the first step of disposing a coil between a first frame and a second frame, the second step of pouring liquid resin into between the first frame and the second frame with the coil disposed therebetween, and the third step of curing the liquid resin to thereby fix the first frame, the second frame and the coil to one another.
Claims15
A heating apparatus comprising:
- a coil to be energized for generating a magnetic flux, said coil having a coil forming surface formed by an arrangement of a coil wire;
- a heat generating member that generates heat by the magnetic flux from said coil;
- a coil supporting member that supports one surface of said coil forming surface, said coil supporting member being disposed opposite to said heat generating member;
- and
- a restraining member disposed in close proximity to and opposite to the other surface of said coil forming surface for restraining a movement of said coil,
- wherein said coil is fixed by pouring resin in a state in which a movement of said coil forming surface between said coil supporting member and said restraining member is restrained.
