An ink jet printing apparatus comprising:

an ink tank for each ink color that stores ink to be supplied to a print head that ejects ink;
an ink flow path plate for each ink color, the ink flow path plate having a supply flow path that guides the ink supplied from the ink tank to the print head;
a flow path concentration plate in which is concentrated the supply flow path for each ink color and which guides the ink between the ink flow path plate and the print head, the flow path concentration plate being inclined with respect to the ink flow path plate;
and
one or a plurality of function parts provided within a space demarcated by both of (a) the ink flow path plate and (b) the flow path concentration plate, the one or a plurality of function parts being configured to act on the supply flow path inside the ink flow path plate.
