Abstract: Disclosed is a complex protection device including a substrate, fuse terminals provided on the substrate, first resistive terminals provided on the substrate so as to be separated from the fuse terminals, second resistive terminals provided on the substrate opposite to the first resistive terminals across the fuse terminals, a fusible element connected to the fuse terminals, a first surface-mounted resistive element connected to the first resistive terminals, a second surface-mounted resistive element connected to the second resistive terminals, at least one printed resistive element connected to at least one of the first resistive terminals and the second resistive terminals and connected to at least one of the first surface-mounted resistive element and the second surface-mounted resistive element, and a switching element controlling flow of current to the first and second surface-mounted resistive elements and the at least one printed resistive element if overvoltage is applied.
