Disclosed is an array (1) with fine protrusions, which is provided with a substrate (2), and fine protrusions (3), each of which is provided on the substrate (2), and is tapered toward the leading end portion from the bottom portion. When the distance between the leading end portion and the bottom portion, said distance being on a discretionary side surface of the fine protrusions (3), is expressed as (a), and the length of a second segment formed by projecting a first segment on the substrate (2) is expressed as (b), said first segment indicating the distance (a), the following relationship is satisfied: 1.0<(a/b)=7.5. |
