PROBLEM TO BE SOLVED: To provide a printed board that can be used even in a place where spatial constraints to the radial direction of a conductor 66 for electric power transmission are more than before, and has a current transformation function.SOLUTION: A coil-shaped wiring 10 comprises wiring patterns 12, 13 formed in two layers of a printed board, and a through hole 11 penetrating the two layers of the board. Also, when a conductor 66 for electric power transmission is arranged so as to be adjacent to the printed board, the coil-shaped wiring 10 is arranged on the printed board for current detection so that the axial direction of the coil-shaped wiring 10 is vertical to the axial direction of the conductor 66 for electric power transmission, and the axial direction of the through hole 11 is vertical to the axial direction of the conductor 66 for electric power transmission. Consequently, even at a place where spatial constraints are more than before, current can be detected. |
