摘要： Activated carbon for an electrode of an electric double-layer capacitor is produced by subjecting a carbon material sequentially to a carbonizing treatment and an alkali activating treatment, and by using a carbon material. The carbon material used is a condensed polycyclic aromatic compound (CPAC) which has a condensed ring (CR) and at least one aliphatic hydrocarbon radical (R) bonded to said condensed ring (CR). The condensed ring (CR) includes at least one alicyclic hydrocarbon structure moiety (ALC). In an analysis chart resulting from a 13C-NMR spectroscopy of the condensed polycyclic aromatic compound, a signal intensity ratio IL/IR is equal to or larger than 0.2, and a signal intensity ratio IC/IR is equal to or larger than 0.14, wherein IR represents a signal intensity of an aromatic peak; IL represents a signal intensity of an aliphatic hydrocarbon peak; and IC represents a signal intensity of an alicyclic hydrocarbon peak. Thus, activated carbon of a low electrostatic capacity revealing voltage and a high electrostatic capacity density (F/cc) can be produced by using a particular carbon material.

In cases where such activated carbon is used as a raw material in electronic devices, the formation of dendrites by the reductive deposition of alkali metals or heavy metals tends not to occur, so that problems such as short-circuiting or the like tend not to arise, and a good rate of self-discharge retention is shown.
