Zusammenfassung:	To prevent molding failure in manufacture of a resin substrate while manufacturing a micro flow channel chip using a resin substrate having flow channel grooves at low cost.SOLUTION: A micro flow channel chip (1) includes a resin substrate (2) having flow channel grooves (21) on one surface, and a covering material (3) joined to the resin substrate (2) so as to cover the flow channel grooves (21). An arithmetic average height Sa measured according to ISO 25178 of a joint surface (2a) to the covering material (3) in the resin substrate (2) is 0.1 μm or less, and an arithmetic average curvature Spc of a mountain top is 150 mm-1 or more and 500 mm-1 or less.SELECTED DRAWING: Figure 1 【課題】流路溝を有する樹脂基板を用いて低コストにマイクロ流路チップを製造しつつ、樹脂基板の製造時における成形不良を生じにくくする。【解決手段】マイクロ流路チップ（１）は、一方の面に流路溝（２１）を有する樹脂基板（２）と、流路溝（２１）を覆うように樹脂基板（２）に接合される被覆材（３）とを備える。樹脂基板（２）における被覆材（３）との接合面（２ａ）の、ＩＳＯ２５１７８に準拠して測定される算術平均高さＳａが０．１μｍ以下で、かつ、山頂点の算術平均曲率Ｓｐｃが１５０ｍｍ－１以上５００ｍｍ－１以下である。【選択図】図１
