Protective element and method for producing the same

A method for producing a protective element for interrupting an electric current, the method comprising:

• a first step of applying a solder, having a liquid-phase point higher than a mounting temperature at which the protective element is mounted to a protection target device, on a plurality of electrode terminals formed on a prescribed substrate in such a manner that a current-carrying path is divided into plural to form an electric current interruption portion;
• a second step of, mounting a prescribed elastic so as to be laid across the plural electrode terminals applied with the solder;
• and
• a third step of adhering the elastic member firmly to the plural electrode terminals in a state that the elastic member is urged by allowing the solder to be cooled down after being heated and melted in a state that the elastic member is flexed in contact with the solder,
• wherein the third step allows the elastic member to be soldered onto the electrode terminals in a state that the elastic member maintains a level of stress allowing at least one of the plural electrode terminals to be separated therefrom by deformation of the solder even in a state that the solder is not completely melted.

• wherein the third step enables the elastic member to be soldered onto the electrode terminals in a state that the elastic member maintains a level of stress allowing at least one of the plural electrode terminals to be separated therefrom by deformation of the solder even in a state that the solder is not completely melted.
