PROBLEM TO BE SOLVED: To accurately detect a voltage to be detected. ! SOLUTION: A detection sensor comprises: a pair of clip pieces 2, 3 coupled rotatably each other via a rotary shaft 4 disposed in each of coupling parts 21a, 31a, and provided with holding parts 22a, 32a on each of tip sides 22, 32 from the coupling parts 21a, 31a; a detection element 61, disposed in at least an internal space 26 which is one of internal spaces 26, 36 provided in the clip pieces 2, 3, for detecting the voltage of a held-state electric wire 200 held by each of the holding parts 22a, 32a; and guard electrodes 8, 9 of the same potential as a predetermined reference potential. The guard electrodes 8, 9 are disposed, in each of the internal spaces 26, 36, so as to face the held-state electric wire 200 while being separated from the detection element 61, without shielding a detection area 61a of the detection element 61 by the guard electrodes 8, 9. !
