PROBLEM TO BE SOLVED: To allow fluid to be injected even when a pressure is further from a target pressure while performing suppression of reducing a period of time until the fluid is injected.SOLUTION: A fluid injection device comprises: a fluid injection section causing 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; and a pressure adjustment section adjusting a pressure in the fluid container such that the pressure is closer to a target pressure than a first threshold value related to the pressure in the fluid container. The injection control section has a first injection mode and a second injection mode as an injection mode, receives an injection request of the fluid when the pressure in the fluid container is closer to the target pressure than a second threshold value further from the target pressure than the first threshold value in the first injection mode and receives the injection request even when the pressure in the fluid container is not closer to the target pressure than the second threshold value in the second injection mode. |
