Abstract

[Problem] To provide a fluid injection device capable of efficiently administering a drug. [Solution] A first transport body 11 includes a first transport flow path through which a first fluid 21 flows, and a second transport body 12 includes a second transport flow path through which a second fluid 22 flows. A positive-side microneedle 13 has a first opening and a first flow path having a fixed positive charge, and is provided in the first transport body 11. A negative-side microneedle 14 has a second opening and a second flow path having a fixed negative charge, and is provided in the second transport body 12. The current/voltage application means 15 is configured so as to be capable of applying a current or voltage between the first electrode 24 disposed in the first transport flow path and the second electrode 25 disposed in the second transport flow path. When a current or voltage is applied, an ionic current flows through the first fluid 21 and the second fluid 22, and due to electroosmotic flow, the first fluid 21 flows outward from the first opening, and the second fluid 22 flows outward from the second opening.
