PROBLEM TO BE SOLVED: To provide a channel member which causes a seal member to be easily attached, and reduces the coming off of the seal member at an unanticipated timing by preventing reactive force by the seal member from increasing significantly, and to provide a liquid jet head and a liquid jet apparatus.SOLUTION: A channel member includes: a channel member body 310 provided with a liquid supply channel 311 for supplying liquid to a head body that discharges liquid, and a fitting part 316 in which one end of the liquid supply channel 311 opens and to which a liquid supply means 20 for supplying the liquid in the liquid supply channel 311 is fitted; a filter 317 fixed to the fitting part 316 that covers the opening of the liquid supply channel 311; and a seal member 330 formed of an elastic material which is provided around the fitting part 316. The seal member 330 is provided with an insertion hole 334 into which the fitting part 316 is inserted. The inner surface of the insertion hole 334 is provided with a projection 335 that projects to the fitting part 316 side and closely contacts the fitting part 316. In the region other than the projection 335, a space is defined between the insertion hole 334 and the fitting part 316. |
