The coil in which the winding type choke coil can be mounted on the substrate is obtained by housing the solder-plated winding coil 1 in a resin container 3 having pin terminals, and placing the coil terminal 2 in a through hole 4 provided in the bottom of the resin container 3. It was inserted and its tip was inserted into a printed circuit board (not shown) and soldered. The resin container 3 has a block shape. In addition to the through hole 4 at the bottom, a crescent-shaped concave portion is formed on the upper surface, and standoffs 5 are provided at four lower corners.

In FIG. 2, a coil housing recess 14 is formed on the upper surface of a block-shaped resin container 13, and the coil housing recess 14 can be stored about 2/3 below. The exterior of the resin container 13 has a crescent shape, a lead-out groove 17 is dug in a side surface thereof, a pin terminal 16 is buried in a lower portion, and a standoff 15 is provided diagonally in a lower portion. Two are provided. The coil terminal 12 is fixed to the lead-out groove 17 and is led out downward. Further, the bottom surface is guided to the opposite side crossing the pin terminal 16 and led to the standoff 15 on the left side in the figure. The standoff 15 is provided with a V-shaped guide 18 and a semicircular fixing groove 19 for guiding and fixing the coil terminal 12.

続を行う。FIG. 3 is a view of the formed state after the coil is installed, as viewed obliquely from below. The coil terminal 12 is fixed by the fixing groove 19. The end of this terminal does not protrude from the side of the case, and this end is sufficiently shorter than the width of the fixing groove 19. Electrical and mechanical connections are made by resistance welding at the intersections of the coil terminals 12 and the pin terminals 16.
