Abstract

There is provided a master for micro flow path creation, a transfer copy, and a method for producing a master for micro flow path creation by which transfer copies having an area with high hydrophilicity can be easily mass-produced, the master for micro flow path creation including: a base material; a main concave-convex portion provided on a surface of the base material and extending in a planar direction of the base material; and a fine concave-convex portion provided on a surface of the main concave-convex portion and having a narrower pitch than the main concave-convex portion. The fine concave-convex portion has an arithmetic average roughness of 10 nm to 150 nm and has a specific surface area ratio of 1.1 to 3.0.
