PROBLEM TO BE SOLVED: To provide a body cleaning foam supply device in which a foaming ratio of foam is optimally set and homogeneous foam is generated, and thereby a feeling of satisfaction "fully washed" can be provided for a bather, while reducing an adverse effect of "rubbing too much and washing too much", and a physical burden can be reduced for a caretaker, retentivity (adhesive) is good, the texture of foam is superior and the foam can be quickly applied.SOLUTION: A body cleaning foam supply device of the present invention includes: water supply piping 31 for supplying water from waterline piping 30 or a water storage tank to a shower head 6； liquid cleaner supply piping 32 for guiding liquid cleaner to the water supply piping 31； and gas supply piping 33 for guiding gas to the water supply piping 31. A cleaner mixing part 34 to the water supply piping 31 of the liquid cleaner supply piping 32 is provided upstream of a gas mixing part 35 to the water supply piping 31 of the gas supply piping 33.
