Abstract

A recording apparatus includes a head, wherein a manifold in which an ink flows, and a plurality of ink flow paths divided from the manifold and arranged in a first direction are formed in the head; a nozzle opening portion discharging the ink flowing from the manifold is formed in the ink flow path; when a maximum area is C1 and a minimum area is C2 in a cross section of the ink flow path including the first direction and a vertical direction, except a cross section including the nozzle opening portion, the C1 is more than once and equal to or less than 3.5 times the C2; a length of the longest line segment among the line segments parallel to the first direction in the cross section of the ink flow path including the first direction and the vertical direction is 30 µm or more and 80 µm or less ; and the ink contains a flaky pigment having an average thickness of 5 nm or more and 50 nm or less and a 50% average particle diameter of an equivalent circle diameter of 0.5 µm or more and 2.1 µm or less.
