Abstract:
A flow path member includes a first space which is opened by a first liquid flow path, and into which liquid flows from the first liquid flow path; a second space which is opened by a second liquid flow path on a bottom surface at the opposite side to the first space, and out of which liquid flows from the second liquid flow path; a filter which filters liquid passing therethrough, and which is included between the first space and the second space; and a support which protrudes from the bottom surface of the second space toward the filter side, in which the support is a point-form projection.
