<p><P>PROBLEM TO BE SOLVED: To provide a liquid jetting head and a liquid jetting device, configured to have reduced number of parts to reduce material cost and assembling cost, while preventing leakage of liquid. <P>SOLUTION: The liquid jetting device includes: a circuit board 40 disposed between a head body 30 and a flow channel member 20, and having larger area than the head body 30; and a lid member 50 in contact with the head body 30 circumferentially on the outside of a liquid jetting surface and in contact with the flow channel member 20 circumferentially on the outside of the circuit board 40, to form space for hermetically sealing the circuit board 40 between the flow channel member 20 and the head body 30. An inner circumferential seal member 55 for hermetically sealing the lid member 50 and the head body 30 is formed in one of the lid member 50 and the head body 30 by two-color molding, and an outer circumferential seal member 52 for hermetically sealing the lid member 50 and the flow channel member 20 is formed in one of the lid member 50 and the flow channel member 20 by two-color molding. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
