Abstract

An optical voltage probe including: an optical modulator 1 having two modulation electrodes 11, 12 configured to modulate an intensity of an incident light depending on a voltage between the two modulation electrodes 11, 12 and output the modulated incident light; an input/output optical fiber 2 connected with the optical modulator 1; two contact terminal attachment portions 5, 6 to which two contact terminals 3, 4 can be detachably attached and contacted, the two contact terminals 3, 4 being connected with the modulation electrodes 11, 12 and in contact with points to be measured; and a package 8 that houses the optical modulator 1 and a part of the input/output optical fiber 2, wherein a voltage signal induced via the contact terminals 3, 4 is converted into an optical intensity modulation signal and outputted, and the package 8 covers an inside with a metal body 8a for shielding electric field and a magnetic shielding material 8b for shielding magnetic field.
