ELECTROLYTIC CAPACITOR AND MANUFACTURING METHOD THEREOF

To provide an electrolytic capacitor improved in the connectability between a negative electrode body including a carbon layer and a lead terminal, and a method for manufacturing the electrolytic capacitor.SOLUTION: An electrolytic capacitor 1 comprises: an anode body 2 with a dielectric oxide coating 5 formed on its surface; a cathode body 3 having cathode foil 31 and a carbon layer 32 formed on the cathode foil 31; a liquid electrolyte 6 interposed between the anode body 2 and the cathode body 3; and lead terminals 7 cold pressure welded to the anode body 2 and the cathode body 3. The maximum static friction coefficient of the surface of the carbon layer 32 of the cathode body 3 is 0.6 or more.SELECTED DRAWING: Figure 1 【課題】カーボン層を含む陰極体と引出端子の接続性が改善された電解コンデンサ及びこの電解コンデンサの製造方法を提供する。【解決手段】電解コンデンサ１は、表面に誘電体酸化皮膜５が形成された陽極体２と、陰極箔３１及び当該陰極箔３１に形成されたカーボン層３２を有する陰極体３と、陽極体２と陰極体３との間に介在する電解液６と、陽極体２及び陰極体３と冷間圧接された各極の引出端子７とを備える。陰極体３のカーボン層３２の表面の最大静止摩擦係数は０．６以上である。【選択図】図１
