ABSTRACT:
In a plane perpendicular to an axial direction of a winding drum, side legs face each other along an X-direction. A Y-direction is perpendicular to the X-direction. A planar coil component is configured so that a point along the Y-direction, where width of a central leg is maximum along the X-direction is at a plus side of the Y-direction, in relation to a center of the Y-direction, of the central leg; width of the central leg along the X-direction monotonically decreases from the point; width of the central leg along the X-direction is longer than along the X-direction; distance between facing surfaces of the side legs is constant; the terminal board is on the minus side, along the Y-direction, of a flange; and an end of the winding extends through the flange at the minus side of the Y-direction.
