PROBLEM TO BE SOLVED: To place a larger shield material in the periphery of a detection electrode.SOLUTION: A clamp type sensor according to the present invention has: a sensor part Sv for detecting the voltage of a measurement object electric wire and provided with a pair of clamp parts 3a, 11 and configured so as to be able to clamp the measurement object electric wire; and a sensor part Sa for detecting a current flowing in the measurement object electric wire and provided with a pair of clamp parts 4a, 12 and configured so as to be able to clamp the measurement object electric wire. Both sensor parts Sv Sa are disposed side by side, the clamp parts 11, 12 are integrally formed, and a support part 10 continuous in the width direction of both clamp parts 11, 12 is formed. A detection electrode 31 for detecting a voltage is disposed at a portion of the support part 10 that corresponds to the clamp part 12, and a shield material (shield electrode 32 and shield member 22 of the same potential as the former) for shielding the detection electrode 31 is disposed over each portion of the support part 10 that corresponds to the clamp parts 11, 12.SELECTED DRAWING: Figure 3 |
