Kind Code:
A1
Abstract:
A protective element (1a), having: an insulated substrate (10); a first electrode (11) and a second electrode (12) provided on the upper surface (10a) of the insulated substrate (10); a heating element provided on the upper surface (10a) of the insulated substrate (10); a first heating element electrode (13) and a second heating element electrode (14) connected to the heating element; a third electrode (16) connected to the second heating element electrode (14) through a draw-out line (15); a low-melting-point metal (30) disposed on the third electrode (16); a first short wire (31) connecting between the first electrode (11) and the low-melting-point metal (30); and a second short wire (32) connecting between the second electrode (12) and the low-melting-point metal (30). The protective element is configured so that the low-melting-point metal (30) melts, thereby corroding and melting a part of the first short wire (31) and the second short wire (32) in contact with the low-melting-point metal (30).
