Abstract
An endoscope comprises: an insertion portion to be inserted into a body cavity; an operation portion continuously provided from a proximal end side of the insertion portion; and a suction section that performs suction from an distal end of the insertion portion, wherein the suction section comprises: a cylinder in which a gas is compressed and filled; a nozzle unit that generates a negative pressure inside the nozzle unit by jetting out the gas in the cylinder; and a liquid receiver tank communicated with the distal end of the insertion portion, the negative pressure inside the nozzle unit being transmitted to the liquid receiver tank.
