Liquid jet head and liquid jet device

Abstract

To provide a liquid jet head that is configured so that cure shrinkage of an adhesive hardly deforms a fixed plate, and a liquid jet device.SOLUTION: The liquid jet head comprises: a first head chip 8 which has a plurality of first nozzles that jet liquid in a first direction and a first common liquid chamber communicated with the plurality of first nozzles; a flow passage structure having a first flow passage 400 communicated with the first common liquid chamber; a fixed plate fixed with the first head chip 8; and a first adhesive 201. The first head chip 8 has a first flow passage pipe 43 having a first connection flow passage 43a communicated with the first common liquid chamber therein and protruding in a second direction from a surface pointing to a second direction which is the opposite direction of the first direction. The flow passage structure has a first opening 225 into which the first flow passage pipe is inserted. The first adhesive 201 arranged between an outer peripheral surface of the first flow passage pipe 43 and an inner peripheral surface of the first opening 225 liquid-tightly connects the first flow passage 400 to the first connection flow passage 43a.SELECTED DRAWING: Figure 4
