Abstract:
A bifurcation path and a flow path which communicates with the head main body through the bifurcation path are provided. The bifurcation path includes an upstream-side path and a downstream-side path. In a plan view of a flow-path forming surface including the bifurcation path and the flow path, the flow path is disposed in a state where an angle between a flowing direction in the flow path and a flowing direction in the downstream-side path is an acute angle. In addition, an angle between a first wall surface of the flow path, which is the wall surface located downstream from the upstream-side path, and a second wall surface of the upstream-side path, which is the wall surface connected to the first wall surface, is equal to or less than 90°. Furthermore, the second wall surface of the upstream-side path has an R shape.
