Abstract:
Provided is a protection element wherein a soluble conductor stably and speedily fuses when protecting operation is performed with an excess current and the like. The protection element is provided with a soluble conductor (13), which is arranged on an insulating base substrate (11), is connected to the power supply line of an apparatus to be protected and fuses with a predetermined abnormal power, and an insulating cover (14) which covers the soluble conductor (13) and is attached to the base substrate (11). The protection element has a flux (19) which is applied on the soluble conductor (13) and is provided in the insulating cover (14). The soluble conductor (13) is fixed to a conductor layer (17) and an electrode (12) on the base substrate (11) by means of a solder paste (20), which contains a metal component having excellent wettability to the molten soluble conductor (13). The solder paste (20) spreads further outward than the periphery of the soluble conductor (13) on the electrode (12) and the conductor layer (17).
