| 摘要 | 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. | ||

| 主权项 | 1. A flow path member comprising: 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, wherein the second space includes a plurality of second liquid flow paths, and the support projection is included within a region which is interposed between the opening centers of at least two second liquid flow paths in the long direction of the filter. | ||
