PURPOSE: To allow compressive and tensile stresses on a fusible body located between wire connecting terminals to be distributed over the whole fusible body for the prevention of rupture near the junction of the fusible body by forming the peripheral diameter of the fusible body near the junction from smooth curves that form a taper toward the center of the length of the fusible body. ;CONSTITUTION: In a fuse fusible body made of a low melting point alloy, the boundary 4c between a fusing part 4a and a non-fusing part 4b which are located at each end of the fusible body 4 has a peripheral diameter defined by smooth curves forming a taper toward the center of the length of the fusible body 4. Also, the center part 4d is in a rectilinear form. Therefore, compressive and tensile stresses or the like do not concentrate on the junction between the fusible body 4 and a terminal (junction conductor) 5 but are distributed along the overall length of the fusible body 4, so that cracking rupture due to fatigue near the junction can be prevented.;COPYRIGHT: (C)1996,JPO
