ABSTRACT:
Electrodes of a chip coil are provided at no magnetic flux concentrated positions of a core of the chip coil. In other words, the chip coil has a configuration where: lead frames are provided at the center of the length of both brims of the core; conductive parts and the ends of a conductive wire are connected to internal electrodes, which are made of thin metal films and provided on both brims, respectively; and external electrodes are extended so as to protrude from the sides of a core drum. This reduces magnetic loss and prevents deterioration of characteristics and the Q value due to the electrodes.
