A stud bolt assembly can couple two electrical conductive members to each other with stability and reliability in connection while avoiding breakage and deformation of the members upon coupling them to each other and an electrical junction box equipped with the stud bolt assembly. Electrical conductive member 24a and a connecting terminal 90 are mounted on a shaft portion 44 of a stud bolt 36. The electrical conductive member 24a is secured to the connecting terminal 90 by fastening a nut 96 on the shaft portion 44. The stud bolt 36 is displaced in a bolt cover 38 in an axial direction. The electrical conductive member 24a and connecting terminal 90 mounted on the shaft portion 44 are firmly and directly fastened between the nut 96 and a distal end surface 50 of a proximal end side projection 48 of the stud bolt 36.
