PROBLEM TO BE SOLVED: To provide a substrate-mounting circuit wherein, with no degradation in strength of a circuit board, the characteristics of the entire electrical circuit is not affected and adjustment of the electrical circuit is easy with less adjusting time. SOLUTION: At least one electrical circuit (1) 2a is mounted on a printed board 1, which is a circuit board, and the electrical circuit (1) 2a comprises a plurality of adjustment circuit 3, 4, and 5 connectable to a main body part 21. Oval V-shaped grooves 7, 8, and 9 are provided on the upper surface of printed board 1 which faces connection terminals 3e, 4e, and 5e of the adjustment circuits 3, 4, and 5, and related to the connection between the main body part 21 and each of the adjustment circuits 3, 4, and 5, separation at the connection terminals 3e, 4e, and 5e of conductor foil is made easy. By appropriately selecting the adjustment circuits 3, 4, and 5 to be separated, the circuit adjustment with the substrate mounting circuit is easily performed without damaging other circuits.
