This method for producing an anti-fouling coating film includes: a step (1) of coating an ultrafine uneven layer-forming agent that contains at least 1 type of polysilazane as a silica raw material ona surface of a base material having a surface comprising a resin so as to form an ultrafine uneven layer that contains silica and the polysilazane; a step (2) of coating a modification layer-formingagent that contains a reactive organic compound and a polysiloxane or perfluoropolyether on the surface of the ultrafine uneven layer obtained in step (1) so as to form a modification layer that contains the polysiloxane or perfluoropolyether; and a step (3) of coating a lubricating oil that contains a silicone oil or fluorine-containing oil on the surface of the modification layer obtained in step (2) so as to form a lubricating oil layer.
