PROBLEM TO BE SOLVED: To provide a wet type dust collection unit of a good maintenance property wherein a manufacturing cost and a using cost can be suppressed, although being of the wet type dust collection unit which is compact and does not occupy a space, a dust collection capacity is high and an amount of a fluid to be discarded can be suppressed as small as possible. SOLUTION: A water feed room 13 is formed in a unit main body 1 having a suction hole 2 connected to a fan unit, and an air inlet 3 connected to a dust collection unit. A specific amount of water 8 is fed to a dust mixing part 10 from the water feed room 13. Dust mixed from the air inlet 3 and air are mixed in water 8 of the dust mixing part 10. The air is separated in a bubble generating part 11a disposed at an end part position of the dust mixing part 10, and the air is sucked from a bent flow path 7 via filters 15, 16 arranged midway.
