Abstract:
1. A capacitance unit comprising: an anode portion having a first anode unit, a second anode unit and a third anode unit connected between the first anode unit and the second anode unit; an insulating portion disposed on and around the third anode unit, wherein the insulating portion is disposed between the first anode unit and the second anode unit, and the first anode unit is exposed from the insulating portion; a first conductive layer connected to the insulating portion and enclosing the second anode unit; a conductive colloid portion connected to the insulating portion and disposed on and around the first conductive layer; and a second conductive layer connected to the conductive colloid portion and enclosing the first conductive layer, wherein the conductive colloid portion is connected between the insulating portion and the second conductive layer, and the first conductive layer and the second conductive layer are connected with each other to form a cathode portion.
