PROBLEM TO BE SOLVED: To provide a microbubble generator causing little clogging of a channel. SOLUTION: This microbubble generator 10 which feeds pressurized water with dissolved air to a bathtub 90 and generates microbubbles acquired from the dissolved air inside the bathtub 90, includes: a tank 12; a first channel 18 having an upstream end connectable to a water supply source 90 or 200 and a downstream end connected to the tank 12; a water collision member 16 attached inside the tank 12, facing the connection part 18a between the first channel 18 and the tank 12; a pump 22 interposed in the first channel 18 and sending the water in the first channel 18 to the downstream side; an air introduction passage 26 for introducing the air to the inside of the tank 12; an air valve 28 for opening/closing the air introduction passage 26; a second channel 32 having an upstream end connected to the tank 12 and a downstream end connectable to the bathtub 90; and a decompression nozzle 36 installed at the connected part between the second channel 32 and the bathtub 90.
