<P>PROBLEM TO BE SOLVED: To provide a liquid injection head and a liquid injection device which improves ejection quality by enhancing the draining of air bubble in a liquid flow path. <P>SOLUTION: The liquid injection head includes a reinforcement member 48 and a head case 47, each of which includes a first flow path 71 and a second flow path 72, being through-holes configuring part of the liquid flow path. The flow path 71 and the second flow path 72 have first openings 1-1, 2-1 closer to a nozzle and second openings 1-2, 2-2 apart from the nozzle and formed to be smaller than the first openings 1-1, 2-1. The reinforcement member 48 and the head case 47 are connected with an adhesive 77 so that the first flow path 71 and the second flow path 72 are communicated. The adhesive 77 is attached to an exposed section 48a at the outside from the second opening 1-2 of the reinforcement member 48 in the connection surface where the reinforcement member 48 and the head case 47 are connected. <P>COPYRIGHT: (C)2013,JPO&INPIT |
