PROBLEM TO BE SOLVED: To provide a fuse with a plurality of types of membrane resistances with different membrane resistance values only by manufacturing a fuse with one type of a membrane resistance by using one type of resistance paste as a battery protector formed by providing a fuse element interposed between a battery group with the number of cells n (n≥2) or less and a load circuit, and the membrane resistance which fuses the fuse element by the heat generated by energizing and generating heat by a battery group voltage at an abnormal time of the battery on a surface of a substrate. SOLUTION: A resistance value of a total length of the membrane resistance 5 is set with respect to a battery voltage with the number of cells n. A head electrode 51 is provided on a membrane resistance end. A tap electrode 52 is provided in an intermediate position of the membrane resistance which achieves a resistance value corresponding to the battery voltage in response to the number of battery cells (less than n), and a lead conductor 71 or 72 is held on the head electrode 51 or the one tap electrode 52 selected for obtaining the resistance value corresponding to the number of cells of the battery.
