Abstract

A protective device for protecting equipment includes an insulation base substrate, a fusible conductor arranged on the insulation base substrate and connected to a power supply path for the equipment so that the fusible conductor is fused off by a preset abnormal current or voltage, an insulation cover mounted on the insulation base substrate to overlie the fusible conductor via a preset spacing, and a flux coated on a surface of the fusible conductor and disposed in the spacing. The fusible conductor is fused off to break a current path when the abnormal voltage is applied to the equipment. The fusible conductor is secured to a conductor layer and to pair electrodes provided on the insulation base substrate via an electrically conductive paste containing a metal component exhibiting wettability with respect to the fusible conductor in the fused state.
