A structure for screw-tightening and connecting a terminal to an electrical junction box is provided. The terminal mounting structure in the electrical junction box ensures mounting operation with an insertion direction of the terminal obliquely oriented, and prevents heating of the terminal due to power supply. The terminal is secured and connected to a busbar of the junction box by a bolt, with a head and a shaft of the bolt inserted into a vertical opening and a horizontal notched hole of the terminal, respectively. A pair of opposed guiding walls are provided on a junction box body at both sides of the bolt. The guiding wall includes an entrance's side sloping surface obliquely extending from top to bottom, and a straight horizontal surface continuing to the sloping surface. The terminal includes a pair of outward projecting pieces at an upper portion to be slid on the sloping surface and the horizontal surface. A heat release portion extends integrally at an upper portion of a vertical plate portion of the terminal having the vertical opening. Linear indentations are provided on front and back surfaces of the heat release portion to be exposed outside.
