摘要：A flow path groove is formed in the surface of at least one of two resinsubstrates; the two resin substrates are joined with the surface in which the flow pathgroove is formed facing inward; a through-hole having a substantially round cross sectionis formed in either one of the two resin substrates such that the through-hole connectswith the flow path groove from the surface opposite the surface where the two resinsubstrates join; protruding parts, which protrude in the direction of thickness of the resinsubstrates and are disposed enclosing the through-hole, are formed in the surface onthe opposite side; a space, which has a substantially round cross-sectional shapeconcentric with the through-hole and has depth in the same direction as the direction ofthickness of the resin substrates, is formed in the joined surfaces when the protrudingparts are projected from the direction substantially perpendicular to the joined surfaces;and the correlation of fc>fa is satisfied when the edges on the base end side of thethrough-hole are projected onto the joined surfaces from a substantially perpendiculardirection, where the diameter on the base end side of the through-hole is fa and thediameter on the end edge side of the space touching the joined surfaces is fc.
