Abstract
Nozzle rows that discharge the same liquids are disposed at locations symmetrical about a reference line. The flow path member includes a first flow path member, a second flow path member joined to the first flow path member, a filter retainer member that is joined to the second flow path member and that holds filters, a third flow path member that is joined to the filter retainer member. The liquid flow path includes first horizontal flow paths that are provided between the first flow path member and the second flow path member and that divide the liquid supplied from the liquid supply unit and buffer chambers provided on the first horizontal flow paths. Between the second flow path member and the filter retainer member, filter chambers are provided in regions that face the buffer chambers. The buffer chambers communicate with central portions of the filter chambers.
