Abstract

PURPOSE: To surely prevent a treating fluid from reaching the nontreatment surface of a material to be treated by superposing a mask member on the nontreatment surface with a sealant in-between, pressing the material and the member, and bringing them into contact with the treating fluid.
CONSTITUTION: For example, circular Al plates 1, 1 to be treated are superposed on each other with circular PVC sheet 2 of the same diameter between nontreatment surfaces 1a, 1a of plates 1, 1. Ringlike cramp 3 made of heat and corrosion resistant resin such as fluororesin is pressed on the outer peripheral part of superposed plates 1, 1. Thus, plates 1, 1 closely contact with each other with sheet 2 inbetween. By dipping this assembly in a treating fluid contg. heated hydrochloric acid or the like, minute uneven etched surfaces 5 are formed on plates 1, 1 except surfaces 1a, 1a. In this case, one plate 1 acts as a mask member to the other plate 1.
