Summary:PURPOSE: To increase the number of winding per unit area in a high-frequency induction coil used for preliminarily heating a surface of an injection molding device by high-frequency induction heating while the size increase of an inductor incorporated in the high-frequency induction coil is minimized. CONSTITUTION: In a high-frequency induction coil A, a right hand wind spiral coil 1 and a left hand wind spiral coil 2 are overlapped and connected to each other at the center thereof. In this manner, the two spiral coils 1, 2 can be serially connected to each other without interposing a lead wire between the spiral coils 1, 2, whereby the number of winding per unit area can be doubled.
