Summary:PURPOSE:To make the title element small in size as well as to make it possible to quickly and stably cut a fuse part by fusing by a method wherein a fuse part, which will be cut by fusing when a current in excess of the prescribed value flows to an internal conductor, is integrally provided, and the fuse part is provided in a cavity part. CONSTITUTION:The width of an internal conductor 6 is narrowed about in the middle part in the degree with which the conductor 6 will be cut by fusion when a current in excess of the prescribed value is allowed to flow, and said narrow-widthed part formed in the middle of the internal conductor 6 constitutes a fuse part 10. Accordingly, it is unnecessary to provide a fuse independent of an inductance element 2 as a safe measure. Also, as the fuse part 10 is provided in a cavity part 12 in the internal part, the Joule heat of the current flowing to the fuse part 10 effectively works on the fusing of the fuse part 10. As a result, the title inductance element can be made small in size, and at the same time, the quick and stable fusing of the fuse part 10 can be made possible.
