ABSTRACT:
A wire-circuit sheet includes: a resin sheet with circuit connecting holes, wires lying across the circuit connecting holes , and at least on cutting hole to punch the resin sheet so as to cut simultaneously the wires. Further, a wire-circuit sheet and its manufacturing method include: a resin sheet on which a plurality of wires lie as crossing or coming close to each other, cutting holes being provided at the crossing or close points of the plurality of wires to cut off the wires and the sheet together, and the wires being fixed and sandwiched in between laminated resin sheets with a sticky surface. Moreover, in an electric junction box utilizing the wire-circuit sheet, a busbar-wire connecting method includes the steps of: forming insertion holes through a cover in order to insert and fix busbar-tabs as terminals; inserting the busbar-tabs as terminals into the insertion holes in the cover; mounting a wire-circuit sheet at a predetermined position on the cover; and using the busbar-tabs as welding electrodes to weld the wires and the busbar-tabs together to connect them in a conductive state.
