PROBLEM TO BE SOLVED: To provide a chip type aluminum electrolytic capacitor excelling in its vibrational resistance, wherein the temperature of its each lead wire exposed from its insulating terminal plate to the external is so increased preferentially as to be able to secure its highly reliable soldering property in a comparably relaxed reflow atmospheric environment.
SOLUTION: An insulating terminal plate has two inserting holes for inserting thereinto a pair of lead wires derived from the sealing member of a capacitor main body, and has on its external surface each recessed groove A for so storing therein each lead wire passed through each inserting hole as to bend each lead wire in a right-angled direction, and further, is so mounted on the sealing member as to be contacted with the sealing member. In the chip type aluminum electrolytic capacitor comprising this insulating terminal plate, such constitutions are provided as to bury two metal electrodes in both the inner walls and both the peripheries of each recessed groove A of the insulating terminal plate, and as to expose a portion of each metal electrode to the end surface of the insulating terminal plate and as for a bidirectional recessed groove B to reach the end surface of the insulating terminal plate from each inserting hole of the insulating terminal plate.
