Abstract

An object is to proceed with a contract-concluding process for an operational data transaction simply, conveniently and clearly. A fluid machine including: a driving source; a fluid machine body that generates a fluid by a driving force of the driving source; a controller that has a GUI allowing an external input and output, and controls driving of the driving source; and a communication apparatus that allows communication with an external server via a wired or wireless communication line. In the fluid machine, when transmitting operational information of the fluid machine to the external server, the external server being owned by a third party other than an owner or an authorized person of a legitimate use right of the fluid machine or the external server whose legitimate use right being held by the third party, the controller transmits the operational information after receiving, via the GUI, an input indicating that the operational information is approved to be output to the third party and to be used by the third party.
