ABSTRACT:
A resistor with a thermal fuse includes: a substrate consisting of an insulating material; a wire pattern formed on a surface of the substrate; a gap for electrically cutting off the wire pattern; a plate spring consisting of an electrically conductive material arranged across the gap; an electrically conductive member fixed to one end of the plate spring on a side of the wire pattern and having approximately the same linear conduction coefficient as that of the substrate; a first low melting point alloy for welding the electrically conductive material and the wire pattern provided on one side of the gap; a second low melting point alloy for welding the other end of the plate spring and the wire pattern provided on the other side of the gap; wherein, when the first low melting point alloy is melted, the electrically conductive member is released from the first low melting point alloy so that the plate spring is also released from the wire pattern.
