Abstract
In a solid electrolytic capacitor, resistance welding is carried out to bond a valve metal substrate and a spacer together while controlling a welding current so that only a bonding material provided in spacers and having a relatively low melting point is melted. At least a portion of the bonding material provided in the spacer penetrates an etching part of the valve metal substrate, and thickness Ta of a core part located at a positive electrode part in the valve metal substrate and thickness Tc of the core part located at a negative electrode part satisfy the requirement of |Tc−Ta|/Tc×100≦10[%].
