Abstract
A protective element contains a heat-generating member and a low melting metal member on a substrate. The low melting metal member is caused to blow out by the heat generated by the heat-generating member. The number of locations on the low melting metal member which are able to blow out is larger than the number of locations which are supposed to blow out so that the protective element is endowed with a “fail-safe” function.
Claims4
A protective element, which comprises a heat-generating member and a low melting metal member on a substrate, the low melting metal member is caused to blow out by the heat generated by the heat-generating member, wherein a portion of the low melting metal member is formed on dummy electrodes so that a number of locations in the low melting metal member which are able to blow out is larger than the number of locations which are supposed to blow out.
