PROBLEM TO BE SOLVED: To provide a beverage rich in hydrogen safely and at a low cost.SOLUTION: A hydrogen injector 1 for inserting a needle 23 into an object 60 to be packed with hydrogen and injecting hydrogen into the object through the needle 23, includes a tube 6 connected with an outside hydrogen supply source 81, the hollow needle 23 connected with the tube, a pressing part 2 for pressing out the hollow needle, an elastic member 46 for energizing the pressing part toward a first position from a second position, and a contact member 5 that contacts the object and has an open hole 50 through which the hollow needle can move back and forth. The pressing part is pressed to move the hollow needle from the first position to the second position against elastic force of the elastic member and take out the hollow needle from the open hole of the contact member to project the hollow needle to a position for getting in the object. A hydrogen injection system 70 includes at least the hydrogen injector and a hydrogen supply apparatus 80.【課題】安全でかつ低コストにて、水素を豊富に含んだ飲料を提供する。【解決手段】水素を入れる対象物60に針23を刺し込み、当該針23を通じて水素を対象物に注入するための水素注入器1であって、外部の水素供給源81と接続されるチューブ6と、そのチューブに接続される中空針23と、その中空針を押し出すための押圧部2と、その押圧部を第二位置から第一位置の方向に付勢する弾性部材46と、対象物に当接する当接部材5であって中空針を出し入れ可能な貫通孔50を備える当接部材5とを備え、押圧部を、それを押し込むと弾性部材の弾性力に抗して中空針を第一位置から第二位置へと可動とし、中空針を、当接部材の貫通孔から露出して対象物の内部に入る位置まで突出させる水素注入器、およびそれに水素供給装置80を少なくとも備える水素注入システム70。【選択図】図3
