SOLUTION: An injection device for nutriments, bacteria and bait and comprising a pump and a nozzle is provided. Especially, an injection device having a long and slenderly extended nozzle and plural liquid-exhaust holes on the side surface near the tip end part of the nozzle, and an injection method of nutriments and the like using the device, are provided.
