Claim Text:
1. An inkjet-head comprising: a first flow path member in which a first flow path is formed; a second flow path member in which a second flow path is formed and to which the first flow path member is bonded; and an intra-head flow path, wherein the second flow path has an intra-joint-surface flow path which is formed by surrounding, with a first adhesive, a peripheral edge of a groove formed in the second flow path member and bonding the first flow path member thereto, wherein a joint space is formed and includes the intra-joint-surface flow path due to surrounding, with a second adhesive, an outer periphery of the intra-joint-surface flow path and bonding the second flow path member and the first flow path member, wherein at least a part of an atmosphere opening path which causes the joint space to be open to the atmosphere is formed by sealing an atmosphere opening groove formed in the joint space using a film, wherein at least a part of the intra-head flow path is partitioned by a flexible member which is bent in response to pressure fluctuation, and wherein an intra-head space separated from the intra-head flow path with the flexible member interposed therebetween communicates with the joint space.
