PROBLEM TO BE SOLVED: To provide an electroscope capable of deterring a probe from being driven due to sounding of a buzzer, so as to deter surely the malfunction of sounding repeatingly the buzzer, not by complicated attaching structure of fixing the probe firmly to a printed board side in an extent of a degree not vibrated but by simple structure. SOLUTION: This electroscope 11 is constituted of at least the printed board 13 mounted with at least the buzzer 14, and provided with a required voltage detecting circuit, the thin-film-like probe 15 with a base end part 15a side position-fixed to the printed board 13 to projection-arrange a tip end part 15b thereof along a face direction of the printed board 13, and a casing 16 having a protection cover part 17 for covering a near periphery of the tip end part 15b in the probe 15 to sheath-cover the whole thereof. In the electroscope 11, a grease-like viscous material 18 is filled to restrain the probe 15 from being vibrated in an inside of the protection cover part 17. COPYRIGHT: (C)2006,JPO&NCIPI
