Abstract: An electrolytic capacitor including: an element stack including a plurality of capacitor elements; a package body sealing the element stack; and a first and second external electrode. Each of the capacitor elements includes a first end at which the anode body is exposed, and a second end covered with the cathode section, with at least an end surface of the first end exposed from the package body. The capacitor elements include a first capacitor element in which the first end faces a first surface of the package body, and a second capacitor element in which the first end faces a second surface different from the first surface of the package body. The first and second capacitor elements stacked alternately. The first end of the first capacitor element and the first end of the second capacitor element are electrically connected to the first external electrode and the second external electrode, respectively.

Abstract: A joined structure includes: a first member; and a second member that faces the first member and that is joined to the first member via a joining layer. The joining layer includes a metal material and a solder material, apart of the metal material has at least one pore, and the solder material is located in a part of an internal area of the at least one pore. Also disclosed is a joining method that makes it possible to produce the joined structure. Further disclosed is a joining material used in the joining method. The joining method makes it possible to achieve non-pressurization sintering processes while maintaining high precise thickness of a joining layer between the first layer and the second layer based on the spacer.
