    • [Problem] In a wound-type solid electrolytic capacitor, leakage current that is caused by separation of a hard coating film from the cathode is prevented from increasing.[Resolution Means] A solid electrolytic capacitor is configured to include a wound capacitor element that has an anode (2), a cathode (3) composed of aluminum, a hard coating film (28) formed on a surface of the cathode (3), a separator (4b), and a solid electrolyte layer, and is also configured so that the solid electrolytic capacitor further includes an intermediate layer 18 formed between the cathode (3) and the hard coating film (28), the hard coating film (28) is composed of a compound of aluminum, titanium, and at least one nonmetallic element, and the intermediate layer (18) contains at least one element selected from the group of metallic elements consisting of aluminum and titanium. It is particularly preferable that the hardness of the substance that constitutes the intermediate layer (18) of the solid electrolytic capacitor be less than the hardness of the substance that constitutes the hard coating film (28).
    • [问题]在缠绕型固体电解电容器中,防止了由硬涂层与阴极分离引起的漏电流增加。 [分解方法]固体电解电容器被构造为包括具有阳极(2),由铝构成的阴极(3),形成在阴极(3)的表面上的硬涂膜(28))的卷绕电容器元件, ,分离器(4b)和固体电解质层,并且还被构造成使得固体电解电容器还包括形成在阴极(3)和硬涂膜(28)之间的中间层18,硬涂膜 28)由铝,钛和至少一种非金属元素的化合物组成,中间层(18)含有选自由铝和钛组成的金属元素组中的至少一种元素。 特别优选构成固体电解电容器的中间层(18)的物质的硬度小于构成硬涂膜(28)的物质的硬度。
