う。Problems to be Solved by the Invention
As described in Japanese Patent Application Laid-Open Publication No. H10-260, it is conceivable that the PTC element provided with a groove may not be broken when the PTC element is abnormal. It is conceivable that the state may remain as it is, and there is a problem that the reliability of preventing abnormal heat generation is lacking. Further, since the groove is provided in the PTC element, the PTC element is vulnerable to impact or the like, is easily damaged in normal use, and has poor life resistance. In addition, the cost increases because the groove is formed. Further, the device characteristics are deteriorated due to the influence of the groove.

The spring terminal is made of a spring material such as stainless steel or phosphor bronze. Because of this, there is a problem in that it is resistant to heat, has strength, is hard to be melted, and cannot reliably perform an operation for preventing abnormal heat generation.
