An irrigation/aspiration apparatus capable of detecting an aspiration pressure accurately while preventing an aspirated liquid from entering an aspiration pressure detecting system. The apparatus, which supplies an irrigation liquid to a surgical site and aspirates the supplied liquid with eliminated tissue to be discharged out of a body, has an aspiration channel, a shape-alterable diaphragm in pouch form, including a liquid chamber which communicates with the aspiration channel, a gas chamber which stores and surrounds the diaphragm, and a pressure sensor connecting with the gas chamber via a connecting part.
