1. A method for collecting a fine particle stored in a structure by suctioning the fine particle using a nozzle, wherein, as the structure, a structure in which at least one communication portion that communicates a space storing the fine particle with one surface side and the other surface side of the structure is formed is used, and wherein the structure comprises:
a support layer which has at least one recessed portion formed on one surface of the support layer, and which has a plurality of communication holes that penetrate the support layer in a thickness, wherein some of the plurality of communication holes are positioned within the recessed portion, wherein the recessed portion is capable of storing the fine particle, and a vertical cross-sectional shape of the recessed portion is rectangular, and
a coating layer that covers the surface of the support layer on the recessed portion side, so that only the recessed portion is exposed.
