<p>An electrical junction box for a vehicle has a connector circuit (13) having bus bars (16) fixed on an insulation substrate (17) to connect to electrical connectors, a fuse circuit (14) having bus bars fixed on an insulation substrate (21) to connect to fuses, and a relay circuit (15) having third bus bars (30) fixed on an insulation substrate to connect to relays in use. In assembling the box, in order to avoid generation of stress and allow for dislocation of the circuits, the method includes the steps of: (i) joining upstanding welding portions (16c, 20a) of bus bars of the connector circuit and the fuse or relay circuit by arranging them adjacent each other and welding them together; and (ii) after step (i), joining laterally projecting welding portions (16e, 20b) of bus bars of the connector circuit and the fuse or relay circuits by welding them together when superimposed one on the other. <IMAGE></p> |
