Provided is a method for producing a metallic particle assembly, the method involving a first step for forming a metallic film having an average thickness of 50 nm or less on a substrate, and a second step for changing the configuration of the metallic film into a metallic particle assembly, in which multiple metallic particles are arranged in two dimensions away from one another, by subjecting the metallic film to heat treatment. According to said production method, it is possible to produce a metallic particle assembly which contains, for example, 30 or more metallic particles having an average particle size of 200 to 1600 nm, an average height of 55 to 500 nm, and an aspect ratio defined by the ratio of the average particle size relative to the average height of 1 to 8. |
