Abstract

A method for manufacturing a structure, including photoelectrochemically etching an etching object, the photoelectrochemical etching of the etching object including: injecting an alkaline or acidic etching solution containing an oxidizing agent that receives electrons, into a rotatably held container in which an etching object at least whose surface is composed of group III nitride is held, and immersing the surface in the etching solution; irradiating the surface of the etching object held in the container with light in a stationary state of the etching object and the etching solution; and rotating the container to scatter the etching solution toward an outer peripheral side, thereby discharging the etching solution from the container, after the surface is irradiated with the light.
