    • An electrolytic capacitor having very thin spacer layers is produced by a process in which at least two of the surfaces of an anode valve action metal foil and a cathode metal foil are coated with a photosensitive polymer resin solution; the resultant photosensitive polymer resin solution layers are solidified; the solidified photosensitive polymer resin coatings are masked with a negative or positive masking film having a desired pattern and irradiated with an actinic radiation to partly harden the photosensitive polymer resin coatings in accordance with the masking pattern; after removing the masking film, the irradiated photosensitive polymer resin coatings are developed with a developing liquid to provide spacer layers consisting of hardened portions of the photosensitive polymer resin coatings; the anode and cathode metal foils having the spacer layers are superposed on each other in such a manner that at least one spacer layer is located between the superposed anode and cathode metal foils and at least one other spacer layer is located on at least one of the outside surfaces of the superposed anode and cathode metal foils, to provide a laminate; the laminate is wound into a capacitor element; and then the capacitor element is impregnated with an electrolyte.
    • 通过这样的方法制造具有非常薄的间隔层的电解电容器,其中阳极阀作用金属箔和阴极金属箔的至少两个表面涂覆有光敏聚合物树脂溶液; 所得到的光敏聚合物树脂溶液层固化; 将固化的光敏聚合物树脂涂层用具有所需图案的阴性或阳性掩蔽膜掩蔽,并用光化辐射照射以根据掩蔽图案部分地硬化光敏聚合物树脂涂层; 在去除掩模膜之后,用显影液显影照射的光敏聚合物树脂涂层,以提供由光敏聚合物树脂涂层的硬化部分组成的间隔层; 具有间隔层的阳极和阴极金属箔以这样的方式彼此重叠,使得至少一个间隔层位于叠置的阳极和阴极金属箔之间,并且至少一个其它隔离层位于至少一个 叠置的阳极和阴极金属箔的外表面,以提供层压体; 将层压体卷绕成电容器元件; 然后用电解质浸渍电容器元件。
