The purpose of the invention of the present application is to provide a multipolar fusible link which can decrease in lateral width without increasing in overall height. This multipolar fusible link (100) is provided with an input terminal (110), a bus bar (120) through which the current inputted from said input terminal (110) flows, and multiple terminals (140) connected to the busbar (120) via a fusible part (130), and is characterized in that, by changing the shape of the lower end (122) of the busbar (120) to which the fusible part (130) is connected, the width between the lower end (122) and the upper end (121) opposite of the lower end (122) changes in accordance with the fusible part (130) connected to the lower end (122), and further, the shape of the fusible part (130) connected to the lower end (122) changes, decreasing in lateral width.
