Classification: CPC C | IPC C

Claim 3:
4. The film formation device for the metallic coating according to claim 3,
wherein the control device further includes:
a remeasurement execution unit that causes the measurement execution unit to execute a remeasurement of the alternating current impedance by the impedance measurement device after the re-tensioning of the solid electrolyte membrane by the re-tensioning execution unit;
a film formation redetermination unit that determines to permit the film formation of the metallic coating when the imaginary component of the alternating current impedance remeasured by the remeasurement execution unit is equal to or more than the preliminarily set film-formable value at which the film formation becomes performable, and determines to inhibit the film formation of the metallic coating and permit an etching of the substrate when the imaginary component is smaller than the film-formable value; and
an etching execution unit that etches the surface of the substrate by causing the pressing mechanism to press the substrate by the solid electrolyte membrane, and causing the power supply unit to invert poles of the anode and the substrate that serves as the cathode and apply a voltage until the imaginary component reaches the film-formable value when the film formation redetermination unit has determined to permit the etching,

wherein the film formation execution unit forms the metallic coating by causing the pressing mechanism to press the substrate by the solid electrolyte membrane and causing the power supply unit to apply the voltage when the film formation redetermination unit has determined to permit the film formation and when the etching execution unit has completed the etching.
