Abstract
An endoscope system includes an endoscope having internal conduits, a cleaning solution supply portion formed in the endoscope and communicating with the internal conduits, and a solution feed unit for feeding a cleaning solution to the cleaning solution supply portion. The internal conduits are formed such that the cleaning solution supplied from the cleaning solution supply portion to the internal conduits by the solution feed unit flows in all the flow paths of the internal conduits at a flow speed almost equal to that in the cleaning solution supply portion.
