An aluminum electrolytic chip capacitor having excellent resistance against vibrations is disclosed. The capacitor is free from breakage of soldered portions or lead wires due to the vibrations upon being mounted on a board. The capacitor includes a metal case accommodating a capacitor element and having its open end sealed with a sealing member, and an insulated terminal plate mounted on the case. The case is provided with an annular shrink portion at the sealing of the open end. The terminal plate includes wall portions disposed at positions other than on a line of the lead wire bending direction of the periphery of the terminal plate. The wall portions cover at least the shrink portion. Inner surfaces of the wall portions abut the periphery of the case, thereby holding the case.
