摘要： A protective device is provided that allows a fusible conductor to be fused off quickly in stability at the time of protective operation against over-current or the like. The protective device includes a fusible conductor 13 and an insulation cover 14 mounted on a base substrate 11 to overlie the fusible conductor 13. The fusible conductor, arranged on an insulating base substrate 11 and connected to a power delivery path of equipment to be protected, is fused off by a preset unusual power. The protective device also includes a flux 19 coated on the fusible conductor 13 and provided within the insulation cover 14. The fusible conductor 13 is immobilized on pair electrodes 12 and a conductor layer 17 on the base substrate 11 via a solder paste 20 containing a metal component exhibiting sufficient wettability against the fusible conductor 13 in a fused state. The solder paste 20, arranged on the pair electrodes 12 and the conductor layer 17, is spread more outwardly than the rim of the fusible conductor 13.
