PROBLEM TO BE SOLVED: To provide a fuse element ensuring bond strength to an insulating substrate and insulation after interruption of a current path and having an opening for releasing the internal pressure.SOLUTION: A fuse element includes an insulating substrate 10, a plurality of electrodes 11, 12 formed on the surface 10a of the insulating substrate 10, a fusible conductor 13 connected between the plurality of electrodes 11, 12, and interrupting the plurality of electrodes 11, 12 by blowing out, and a case 20 having a side face 21 bonded onto the surface 10a of the insulating substrate 10 provided with the fusible conductor 13, and a top face 22 covering the surface 10a of the insulating substrate 10. The case 20 is provided, at a position of the side face 21, excepting the lower part in contact with the surface 10a of the insulating substrate 10, with an opening 23 penetrating into the case 20.SELECTED DRAWING: Figure 3 |
