PROBLEM TO BE SOLVED: To provide a fluid delivery pump capable of suitably delivering highly viscous fluid despite of simple constitution. SOLUTION: The fluid delivery pump 1 is provided with a cylinder 15, a piston 16 which is capable of reciprocatingly moving through the inside of the cylinder 15 and is formed with a hole part 16a, a connection cylinder 18 for connecting a nozzle head 2 and the piston 16, transmitting a pressurizing force applied to the nozzle head 2 and lowering the piston 16, a coil spring 19 disposed on the outer peripheral part of the connection cylinder 18, a stopper 17 which closes the hole part 16a in the state that the piston 16 is arranged on the highest ascending position, an inflow valve mechanism 51 which allows the fluid stored in a fluid storage part 4 to flow into the cylinder 15 in accordance with an ascending movement of the piston 16 and an outflow valve mechanism 52 for allowing the fluid flowing into the cylinder 15 to flow out to the nozzle head 2 in accordance with the movement of the piston 16.
