ABSTRACT:
A basic cell for an electric double layer capacitor has a pair of polarizing electrodes each including a plurality of chip electrodes arranged in matrix or honeycomb pattern. The plurality of chip electrodes are electrically connected by direct contact between each adjacent two chip electrodes for increasing the capacitance and decreasing the internal resistance. Excellent charging or discharging characteristic can be obtained even if the sheet collectors for providing charging or discharging current for the chip electrodes have different specific resistivities along the surface of the sheet collectors. The chip electrodes may be of a truncated pyramid shape for improving resistance against distorting or bending stress applied to the basic cell.
