Abstract: An inkjet-head includes a first flow path member in which a plurality of first flow paths are formed; and a second flow path member in which a plurality of second flow paths are formed and to which the first flow path member is bonded. The second flow paths have intra-joint-surface flow paths, respectively, which are 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. A joint space is formed and includes a plurality of the intra-joint-surface flow paths 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. At least a part of the second adhesive is formed further inside of a straight line connecting an end of one intra-joint-surface flow path on the outer side and an end of another intra-joint-surface flow path on the outer side in joined surfaces.
