The present invention relates to an automobile fuse wherein short circuit of the fuse can be easily identified by naked eye through change of color when a fuse short circuits, and provides an automobile fuse manufacturing method, comprising: the fuse body material mixing step (S1) of mixing 96-99 wt% colored plastic powder and 1-4 wt% transparent irreversible thermochromic pigment powder to prepare a mixture material; the fuse body molding step (S2) of melting the mixture material in an injection molding machine to mold a fuse body containing a thermochromic pigment component in an injection mold at an injection temperature of 300-310 ? and an injection pressure of 1200-1600 kgf/cm2; the fuse body drying step (S3) of drying the fuse body containing a thermochromic pigment component at 100-200 ? for 3-5 hours to reduce the water content of the fuse body to 0.1 wt% or less; and the fuse assembling step (S4) of inserting a fuse where a fuse member is fixed between a pair of terminal members into a pair of terminal insertion grooves and a fuse charge groove of the fuse body containing a thermochromic pigment component, for coupling thereto. If the fuse short circuits, the color of the shift layer coated on fuse body (10) or a color conversion label adhered on the upper surface of the fuse body (10), changes. Accordingly, a short circuited fuse is easily identified with the naked eye, and the fuse can be easily replaced. |
