Abstract
This rigid electronic endoscope has an endoscope having an elongate insertable part connected to the front part of an operating part which is also a holding part on the base side and formed of a solid state imaging device which can output an electric signal by electrically converting an object image in this insertable part and a conductive shielding member sheathing this insertable part. The electric signal obtained by this endoscope is input into a signal processing circuit. The ground terminal of this signal processing circuit is electrically connected to the above mentioned shielding member and is isolated from a ground terminal on the external current source side.
