を目的とするものである。[Object of the Invention] As shown in Fig. 4, the conventional connection method that is the object of the improvement of the present invention is to overlap the tip of the temperature fuse 7 and the tip of the leader wire 2, and then weld them using a DC resistance welding machine from above and below. The electrodes 1o a s lOb were pressurized and connected by spot welding (Fig. 5A). Connections made by spot welding have a temporary strength against tension DK caused by shock and vibration, but have weak strength against bending and are susceptible to peeling and disconnection at the connection, and the wire diameter of the connection is large, resulting in two holes. This has drawbacks such as difficulty in accommodating it in the insulating tube 8. The object of the present invention is to provide a welded connection method that does not have these drawbacks.
