Provided is a liquid supply channel device wherein operability, performance, and appearance of a liquid injector are not damaged even if liquid is supplied from an external tank into the body of a liquid injector, and liquid supply can be prevented from being stopped due to collapse of a channel formation member by a housing cover. Also provided is a liquid injector using the liquid supply channel device. A liquid supply channel device comprises channel formation members (40, 50, 60-63, 70A, 70B, 80) for sectioning and forming at least one bent flow channel including a first channel (31), a second channel (32) extending along a direction intersecting the first channel (31) while communicating with one end thereof, and a third channel (33) extending along a direction intersecting the second channel (32) while communicating with the other end thereof, wherein the channel formation members are arranged along a first housing cover (11) or a second housing cover (12) through a gap between the first housing cover (11) and the second housing cover (12) forming the outer surface of the body (10) of a liquid injector so that liquid is supplied from an external tank (20) into the body (10) of a liquid injector. |
