PURPOSE: To facilitate an operation for connecting the terminals of a coil by providing an extension part to one end of a coil bobbin and providing a projecting part for fixing the terminals of the coil to the extension part.
CONSTITUTION: The terminals 14a of the coil are drawn out onto the extension part 16 and are conducted along the inside of the projections 16, 16b from which the terminals are led across a window part 16a and are wound and fixed to the projections 16c. Two pieces of the terminals 14a of the coil are set to the prescribed positions in the above-mentioned manner. On the other hand, the projecting part 16d for positioning the coil bobbin to a circuit board is formed slender along the extension part 16a to one side edge of the extension part 16 toward the same direction. The terminals of the coil and a conductor pattern are thereby exactly positioned, by which the automation of the connection between both is made possible. The need for a post treatment is eliminated and the generation of a mis-connection or short circuit is obviated as well.
