The invention is equipped with a hydrophilic group generating gas supply portion, an installation stand, an irradiation device, and a flow generation portion. The hydrophilic group generating gas supply portion supplies a hydrophilic group generating gas into the treatment chamber. The installation stand is equipped with an installation plate and a support member. The installation plate has a ventilation portion, and the support member is provided protrusively from the installation plate, and supports the workpiece with an air gap left between the workpiece and the installation plate. The irradiation device irradiates the workpiece with an energy wave that induces activation of the hydrophilic group generating gas. The flow generation portion generates a flow of at least part of the activated hydrophilic group generating gas such that the hydrophilic group generating gas flows via the ventilation portion of the installation plate and flows around into the air gap. |
