Disclosure is a fusible link which prevents a housing from being deformed and discolored due to unnecessary generation of heat in a fuse element. In the fusible link, each of connecting plates includes two elastic engagement pieces and two projections respectively in each of ribs which are formed by folding the two ends of the connecting plate. A housing includes, in the inner wall of a connecting plate insertion hole through which the connecting plate is inserted, a connecting plate slip-off preventive stepped portion to be engaged by the elastic engagement piece and a connecting plate slip-off preventive flange against which the preventive projection is abutted. When the connecting plate is inserted through the connecting plate insertion hole, the engagement portions in the connecting plate are engaged with engagement portions in the housing respectively.
