The upper high-temperature resistant layer 2 and the lower high-temperature resistant layer 3 strengthen the high-temperature resistance of the present double-sided tape from the upper and lower aspects, so that the high-temperature resistance of the present double-sided tape is significantly enhanced. Then, by providing the reinforcing bands 101 made of polypropylene film material, since the polypropylene film material has the effect of high strength, the reinforcing layer 1 has the effect of high strength, thereby strengthening the overall strength of the present double-sided tape and being not easily broken. Then, a plurality of the reinforcing bands 101 are arranged in a staggered manner with respect to each other. Therefore, the plurality of the reinforcing bands 101 can play an effect of mutually assisting and reinforcing each other, further improving the overall strength.
