A cross-sectional area of a portion of the main flow path is substantially constant up to a branch start position or decreases toward the branch start position, and a radius of curvature R of a side wall that connects a side wall of the main flow path and a side wall of the branch flow path is 0.5 mm or less and more than 0 mm.
