ABSTRACT:
A nonreciprocal circuit device wherein upper and lower yokes can easily be fitted together, thereby preventing the deviation between the upper and lower yokes to obtain excellent electric characteristics. The upper yoke is bent in a box shape, and provided with an upper wall and two pairs of side walls of approximately rectangular shape, a lower yoke is bent in a U-shape, and provided with a bottom wall and a pair of side walls opposite to each other. A chamfer and a taper continuous to the chamfer are executed on each end face of a lapped part of the side wall on side walls of the upper yoke. Moreover, a perpendicular part parallel to the upper yoke side wall is formed on a lapped part on the upper yoke side wall.
