PURPOSE: A method for electroplating piezo ceramic surface and an apparatus for electroplating are provided, which the time required for electroplating is shortened and the binding strength of the ceramic is increased. CONSTITUTION: The apparatus comprises a temperature detector (2) detecting the amount of heat emission emitted from the surface of the ceramic substrate (1); a differentiator (3) for distinguishing signals; a comparator (4) comprising a comparison circuit; a controlling circuit for a control switch operating a time relay (5) and a generator (7) for heating dielectric; and an apparatus for opening and closing (15) between both the electrodes (11, 12). The generator (7) is connected to both electrodes (11, 12) and a wire (14) in a space isolated by an insulating plate (13) and a cover plate (16), a dielectric cover (10) and dielectric (9) capable of binding many ceramic substrates (1) are equipped between the electrodes (11, 12), The dielectric cover (10) forms many emission spheres (18) inducing the amount of heat emission from the substrate (1) to the temperature detector (2), and the emission spheres (18) and the temperature detector (2) are connected to a tube of rays (8) having a polymer thin film (17) in the upper part. The ceramic surface is electroplated by pasting a solid of silver-containing metals on the piezo ceramic surface, inserting a ceramic product between the two plates of dielectric material having high tangent angle (0.08-1.0), and heating it at high frequency electromagnetic wave.
