A connecting terminal and a circuit breaking device having the connecting terminal are provided. A plate-shaped second bus-bar 19 welded to a conductive thermit casing 26 through a low melting point metal 23. The bus-bar 19 has an orifice 20 formed to fix a wire with a terminal body by thread fastening and a thin part 51 formed between the orifice 20 and the metal 23 to have a plate thickness smaller than that of the other portion of the bus-bar 19. The thin part 51 is provided with wedge-shaped notches 53. When fastening a screw inserted into the orifice 20 in a clockwise or counterclockwise direction, a stress resulting from the rotation is absorbed by the thin plate 51 and the notches 53 in pairs. Consequently, owing to the absorption, it is possible to restrict the stress from being transmitted to the welding part of the low melting point metal 23.
