To provide a compact needleless syringe which is high in operational reliability and is conveniently used.SOLUTION: A needleless syringe 100 having an electric function includes a needleless syringe body 120, and a needleless injection end 130 for administering a medicine that extends from the needleless syringe body to a distal side. The needleless syringe body includes a housing 3 whose inside is partitioned into a pressure injection chamber 123 and a motor chamber 124, a pressure injection assembly 170 located in the pressure injection chamber, a needleless syringe lock mechanism 180, at least part of which is located in the pressure injection chamber, and a motor assembly 190 located in the motor chamber. Power source can be provided to medicine capturing and injection for the needleless syringe by an electric drive mode of the built-in motor.SELECTED DRAWING: Figure 1 【課題】作動の信頼性が高く、小型であり、使用するのにに便利な無針注射器を提供する。【解決手段】無針注射器本体１２０と、無針注射器本体から遠位側に延びる薬品を投与するための無針注射端１３０とを含む、電動機能を有する無針注射器１００。前記無針注射器本体は、内部が加圧注射室１２３とモータ室１２４に分けられるハウジング３と、加圧注射室内に位置する加圧注射アセンブリ１７０と、少なくとも一部が加圧注射室内に位置する無針注射器ロック機構１８０と、モータ室内に位置するモータアセンブリ１９０とを含む。内蔵モータの電動形態によって無針注射器の薬の取り込みや注射に動力源を提供することができる。【選択図】図１
