1. An electric double layer capacitor comprising:
- a pair of electrodes each including a carbon layer and arranged opposite to each other;
a partition wall separating the pair of electrodes from each other;
a pair of external electrodes each conductively connected to the pair of electrodes; and
an electrolytic solution provided between the pair of electrodes;
whereinthe carbon layer is about 6 μ
m or less in thickness; and
a high-resistance portion is arranged between at least one of the pair of electrodes and the external electrodes conductive thereto and is smaller in cross-sectional area than the at least one electrode and the external electrodes.

Abstract
An electric double layer capacitor includes an anode, a cathode, and an electrolytic solution provided between the anode and the cathode. The anode may be a niobium porous sintered body with an oxide film formed as a dielectric layer on a surface thereof. The cathode allows an electric double layer at an interface with the electrolytic solution. The electric double layer capacitor has a large capacitance and increased voltage.
