Abstract
A coil contains a winding part and a core. The winding part is formed of plural laminated sheets each having a winding pattern. Plural winding patterns are formed on at least one sheet. Each of the winding patterns has a different number of turns, and the winding patterns are formed around the core so as to be coaxial in the same winding direction. The winding patterns formed on the other sheets are connected via a through-hole, and an end of the winding pattern is connected to an input/output portion formed outside of the sheet.
