Liquid ejecting head and liquid ejecting apparatus
A flow path forming substrate has a pressure generation chamber communicating with a nozzle opening; and a communication plate having a supply path communicating with a manifold common to and communicating with the pressure generation chamber. A recess of the manifold opens opposite to the flow path forming substrate. The recess has a first recess, and a second recess deeper than the first recess. Supply paths are open on a bottom surface of the first recess, and are arranged in a first direction between the first and second recesses. An inclined surface inclined toward the bottom surface of the second recess from the bottom surface of the first recess is provided along the first direction. The inclined surface is configured as alternately repeated first and second inclined surfaces with different angles. A pitch of adjacent second inclined surfaces is smaller than a pitch of adjacent supply paths.
