In this etching method, the surface (11a) of a target object (11) is processed by using a corrosive agent to corrode said surface (11a) as a means of solving the problem addressed by the present invention. The etching method comprises: a resist formation step in which resist liquid is inkjet-printed on the surface (11a) so that the resist liquid forms a resist (12); a surface corrosion step in which the side (11a) of the target object (11) on which the resist (12) was formed by the resist formation step is brought into contact with a corrosive agent so that the part of the surface (11a) not having the resist (12) formed thereon is corroded; and a resist peeling step in which the resist (12) is peeled from the surface (11a) after the surface corrosion step. The etching method is characterized by the resist formation step being a step in which the resist (12) is formed using a resist liquid containing a monofunctional monomer or a monofunctional oligomer and a polyfunctional monomer or a polyfunctional oligomer. |
