PROBLEM TO BE SOLVED: To provide an aluminum electrolytic capacitor having superior reliability by solving the problem that a defective connection is easy to occur, in the connection parts of an internal lead and an external terminal. SOLUTION: A through hole provided in an internal lead 2 is made smaller than the outside diameter of an aluminum bed 5, and also the margin of this through-hole is drawn to attain the arrangement that a cylindrical part 2a is integrally provided. Thus, when the aluminum bed 5 is fitted in the through-hole to caulk a distal end, as the caulking is made in a state the inner peripheral surface of the cylindrical part 2a is in contact with the outer peripheral surface of the aluminum bed 5, the internal lead 2 is connected surely and electrically to an external terminal 4, thereby stably producing an aluminum electrolytic condenser with high reliability.
