PROBLEM TO BE SOLVED: To provide a non-reciprocal circuit device is capable of firmly fixing the split pieces of a metal case together even in an environment of high temperatures and a communication device. SOLUTION: An upper case 8 is formed of magnetic metal and equipped with lateral side walls 8a and 8b. The side wall 8a of the upper case 8 is joined to the side wall 4a of a lower case 4, and two outputs 31 are provided to the side wall 8a so as to prevent solder from flowing out. It is preferable that the cutout 31 is as long as half or above the height H of the side wall 8a. By this setup, the side wall 8a is partitioned into nearly three regions, 8c, 8d, and 8e. Bonding solder provided in the region 8d is dammed up by the cutout 31 and kept in the region 8d so as not to spread over a gap between the side walls 8a and 4a. |
