1. A method of manufacturing a coil, comprising:
- preparing a mold having vertically movable fixing pins disposed therein and slidable left and right sidewalls;
seating a magnetic plate on an inner bottom of the mold;
loading the coil on the magnetic plate so that lead parts of the coil are disposed between the fixing pins and the sidewalls of the mold;
sliding the left and right sidewalls of the mold into the mold to closely adhere the lead parts of the coil to the fixing pins;
filling a magnetic slurry in the mold and primarily pressing the magnetic slurry; and
lowering the fixing pins to perform secondary pressing.
