A cutting apparatus 10 includes a case body 12, a storage tank 37, and a movable member 80. The case body 12 internally includes a machining space 19, a housing space A2, and a communication port 27H through which the machining space 19 is in communication with the housing space A2. The storage tank 37 is detachably disposed in the housing space A2 and collects a coolant discharged from a liquid discharger 36 and passed through the communication port 27H. The movable member 80 is disposed between the communication port 27H and the storage tank 37, located at a first position when the storage tank 37 is not disposed in the housing space A2, and located at a second position when the storage tank 37 is disposed in the housing space A2. The movable member 80 at the first position functions as a liquid holder to hold the coolant.
