To provide a flow path member which can lengthen an interval of air bubble maintenance by preventing air bubble stored in an air bubble chamber from contacting with a filter and storing as much bubble as possible without generating inconvenience for example, flow path blockage.
The flow path member 30 includes: ink flow paths 91, 92 which circulate ink from one inlet toward the other outlet; a filter 33 arranged in a surface crossing an ink flow direction in the ink flow paths 91, 92; and the air bubble chamber 95 which is formed in an upstream side of the filter 33 and where the air bubble is stored. The filter 33 is shaped to protrude at a downstream side of the ink flow path members 91, 92, and is formed to have the same shape as a meniscus shape of the ink in the air bubble chamber 95.
