摘要： Burst pressure P of an insulating layer positioned immediately on a fuse layer is defined by using planar width W of fuse layer and thickness t of insulating layer. The value of the planar width W of fuse layer and the value of the thickness t of insulating layer are set such that the value of burst pressure P is at most about 1000 kg/cm.sup.2. The value of the thickness t and the value of the planar width W are set such that the value t/W is at least 0.45 and at most 0.91. Consequently, stable fuse blowing becomes possible while reducing manufacturing cost.
