PROBLEM TO BE SOLVED: To provide a liquid jetting head unit and a liquid jetting device which can connect channels suitably and has improved assembling property.SOLUTION: A liquid jetting head unit includes: a liquid jetting head 10; an upstream channel member 30 having an upstream channel 101; a downstream channel member 40 having a downstream channel 102; a seal member 50 having a tubular part 51 provided with a connection channel 103 therein; and a support part 61. Therein, the upstream channel member 30 and the seal member 50 seal the upstream channel 101 by applying a pressure in a penetration direction of the connection channel 103 of the tubular part 51, the seal member 50 and the downstream channel member 40 seal the downstream channel 102 by applying a pressure in a direction orthogonal to the penetration direction of the tubular part 51, and the support part 61 is brought into contact with an area superimposed on an area onto which the seal member 50 and the upstream channel member 30 apply a pressure, of a surface side opposite to the upstream channel member 30 of the seal member 50. |
