A wired circuit board that can allow precise connection between wired circuit boards with respect to a direction orthogonal to each other with a simple structure, while allowing reduction in size of the wired circuit boards, and a connecting structure of the wired circuit board comprising two wired circuit boards connected to each other with respect to a direction orthogonal to each other. Relay terminals 9 of the circuit suspension board 1 are arranged along one widthwise edge of the circuit suspension board 1, and terminal cutouts 10 cut in a generally semicircular arc shape from one edge thereof toward an widthwise inside thereof are formed in the relay terminals 9. In addition, insulating base layer cutouts 12 are formed in the first insulating base layer 3 to correspond to the terminal cutouts 10. The circuit suspension board 1 and a flexible wired circuit board for relay 21 are electrically connected to each other by fitting bumps 29 formed on suspension terminals 26 of the flexible wired circuit board for relay 21 in the terminal cutouts 10.
