Endoscope

An endoscope comprising:

• an insertion portion;
• a first electronic instrument that is provided inside the insertion portion;
• a second electronic instrument that is provided inside the insertion portion and is supplied with drive power from a separate system from that used for the first electronic instrument;
• a plurality of power limiting portions that limit to a predetermined value or less the drive power that supply to the first electronic instrument and the second electronic instrument respectively via mutually different systems;
• a first wiring of which at least a portion is placed inside the insertion portion, the first wiring electrically connecting one of the power limiting portions with the first electronic instrument and supplying drive power to the first electronic instrument;
• a second wiring of which at least a portion is placed inside the insertion portion, the second wiring electrically connecting another of the power limiting portions with the second electronic instrument and supplying drive power to the second electronic instrument;
• and
• a system separating component which is a ground that is interposed in an electrical separation state between a first connection connecting the first electronic instrument and the first wiring and a second connection connecting the second electronic instrument and the second wiring, the ground being a conductor that continuously extends from one end of the insertion portion to the other end of the insertion portion, and the ground being used in common with both the first electronic instrument and the second electronic instrument.
