Claims

[Scope of utility model registration request]

Coil pattern sections are printed on both the front and back sides of the chip-shaped substrate, and one ends of each of the coil pattern sections are electrically connected to each other via a through hole, and are electrically connected to the side edges of the chip-shaped substrate. A connecting terminal portion is provided at the other end of each of the coil pattern portions in an electrically connected state, and the connecting terminal portion is formed by filling a groove-like portion formed by cutting out a side end surface of the chip-like substrate with a conductor. A printed coil characterized by:
