发明名称 LIQUID JET HEAD AND LIQUID JET DEVICE
摘要 PROBLEM TO BE SOLVED: To provide a liquid jet head which prevents clogging of a filter thereby inhibiting the deterioration and variations etc. of discharge characteristics from occurring, prevents the increase of passage resistance, and enables stable and long term liquid jet, and to provide a liquid jet device including the liquid jet head.SOLUTION: A liquid jet head 20 includes a liquid passage 42. The liquid passage 42 includes: a filter 44 which filters an ink flowing through the liquid passage 42; a first liquid chamber 51 formed at a position which is located at the upstream side of the filter 44 in an ink flow direction; and a second liquid chamber 54 formed at a position which is located at the downstream side of the filter 44 in the ink flow direction. The filter 44 is disposed so that a normal line H direction of an upstream side surface 44a exposed on the liquid passage 42 intersects with a Z direction. A first recessed part 46 is formed at the -Z side in the first liquid chamber 51 relative to a -Z side end part 45 of the filter 44.
