A fluid injecting apparatus includes: a storage portion which stores a fluid to be injected into a living body and a pump portion which injects the fluid into the living body. The storage portion is provided closer to the living body side than the pump portion. In addition, it is preferable that the pump portion include a tube in which the fluid flows, a plurality of fingers which sequentially press the tube, a cam portion which sequentially moves the fingers, and a motor portion which drives the cam portion to rotate.
