    摘要: A manufacturing method for an electrode for an electrochemical capacitor according to the present invention comprises a first process (steps S1-S3) for forming a polarizable electrode layer on a current collector, a second process (step S4) for subjecting the front surface of the polarizable electrode layer formed on the current collector, to an embossment work, and a third process (step S5) for flattening the front surface of the polarizable electrode layer as has undergone the embossment work. In this manner, in the invention, the front surface of the polarizable electrode layer undergoes the embossment work, so that the polarizable electrode layer is effectively compressed, and it is consequently permitted to achieve a high volume capacitance of at least 17 F/cm3. Moreover, after the embossment work, the resulting embossment is flattened, so that porous grains contained in the polarizable electrode layer are prevented from falling off, and it is permitted to ensure a high reliability.
