It is an object of the present invention to provide a large-area near-field light two-dimensional array that is firmly fixed to a substrate and an inexpensive manufacturing method thereof. A conductive member (6), an immobilization layer (2) formed on one surface of the conductive member (6), and a plurality of light scattering particles (4) disposed on one surface (2a) of the immobilization layer (2); , And a near-field light two-dimensional array capable of in-plane light emission by near-field light from each light-scattering particle (4), wherein the light-scattering particle (4) has a particle size of 1 to 100 nm or less The light scattering particles (4) are arranged in a lattice and at equal intervals, and the interval between the adjacent light scattering particles (4) is set to be equal to or smaller than the particle size. The above problem can be solved by using a near-field light two-dimensional array (50) in which surface plasmons can resonate with external light.
