TARGET SUBSTANCE CAPTURING DEVICE

摘要

The purpose of the present invention is to provide a target substance capturing device capable of increasing sensor sensitivity while setting the period of the lattice pattern of a reflection surface to a desired value, and a target substance detection apparatus provided therewith. A target substance capturing device includes a reflection surface in which a plurality of non-flat portions are arrayed and which captures a target substance and reflects applied light. When a natural number of 2 or more is denoted by M and a natural number of 2 or more different from M is denoted by N, an array in which the plurality of non-flat portions are arrayed includes a plurality of unit arrays in each of which the non-flat portions are disposed such that the center of each of the non-flat portions overlaps the position of each of apexes of a figure with M-fold symmetry, and the plurality of unit arrays are disposed such that the center of gravity of the figure with M-fold symmetry overlaps each of the positions of intersection points of a lattice pattern with N-fold symmetry.
