A dehumidification cooling apparatus for an indoor sports facility is provided which is capable of realizing dehumidification and cooling at a low operating cost in the indoor sports facility. This apparatus includes: an ice chamber for turning water into ice and storing it; an air supply-and-exhaust pipe which is disposed from the ice chamber to the indoor sports facility, leads to the ice chamber and leads to the upper space of the indoor sports facility; a fan which is disposed in a supply pipe of the air supply-and-exhaust pipe; and a heater which is disposed in the supply pipe of the air supply-and-exhaust pipe. The fan supplies air cooled with the melting heat of ice made in the ice chamber, from the ice chamber through the supply pipe to the upper space of the indoor sports facility; the heater heats the air inside of the supply pipe, to reduce its humidity to a predetermined level; and through an exhaust pipe of the air supply-and-exhaust pipe, the air of the upper space of the indoor sports facility is returned for circulation to the ice chamber, so that dehumidification and cooling are conducted in the space of the indoor sports facility.
