PROBLEM TO BE SOLVED: To provide a micro-bubble generator capable of eliminating pressure a loss of water which lowers water jetting pressure, and a flush toilet stool device using it. SOLUTION: This micro-bubble generator 1 includes a gas mixing part 3 for mixing gas in water by an ejector effect of water, a micro-bubble generating part 4 for breaking up the gas mixed in water in the gas mixing part3, which are disposed in order from the upstream side. A small diameter part 5 for putting the interior of a water passage 2 in a decompressed state for segmenting the gas is provided in an upstream area of the micro-bubble generating part 4. The region of the water passage 2 extending from the gas mixing part 3 to the small diameter part 5 of the micro-bubble generating part 4 is formed of a diameter reduced part 7 gradually decreased in inside diameter. The inner surface of the water passage 2 extending from the gas mixing part 3 to the small diameter part 5 of the micro-bubble generating part 4 is formed in a shape of a smooth curved surface by the diameter reduced part 7.
