PROBLEM TO BE SOLVED: To reduce a period of time until fluid is injected.SOLUTION: A fluid injection device comprises: a fluid injection section causing a fluid to be injected; an injection control section controlling injection of the fluid from the fluid injection section; a fluid container storing the fluid supplied to the fluid injection section; a connection flow passage connecting the fluid injection section and the fluid container and being a flow passage where the fluid flows; an open/close section opening and closing the connection flow passage; and a pressure adjustment section adjusting a pressure in the fluid container while causing the open/close section to open and close the connection flow passage. The pressure adjustment section adjusts the pressure in the fluid container to be greater than a predetermined pressure in a state of the connection flow passage being closed by the open/close section and causes the open/close section to open the connection flow passage after the pressure in the fluid container is greater than the predetermined pressure. The injection control section causes the fluid injection section to permit injection of the fluid after the connection flow passage is opened. |
