Abstract
The present invention relates to an electrooptic probe that couples an electrical field generated by a measured signal and an electrooptic crystal, makes light incident on this electrooptic crystal, and measures the waveform of the measured signal by the state of the polarization of the incident light. Here, in the probe body,, the probe head,and the supporting member,positioned between the end terminal,and the part that encloses the laser diode,and the photodiodes,and,are formed by an insulating body (polyacetal resin). Furthermore, the photodiodes,and,and the laser diode,are covered by electromagnetic shield members,and,that are separated from each other.
