PROBLEM TO BE SOLVED: To provide a technique by which fluid can be stably circulated.SOLUTION: A fluid circulation device for circulating fluid without contact with outer air includes: a pump chamber that performs the operation for changing a volume an inlet channel which is an inflow channel to the pump chamber a fluid resistance element that controls or inhibits the flow of the fluid toward the inflow channel from the pump chamber an outlet channel that is an outflow channel of the fluid from the pump chamber a circulation flow channel that is a flow channel in which the fluid circulates from the outlet channel to the inlet channel and a pressurizing mechanism that pressurizes the fluid.
