"1. An activated carbon suitable for use in electric double layer capacitors, 
said activated carbon being produced by carbonization of a carbonaceous 
material consisting essentially of coconut shell, wherein said activated carbon 
is produced by a process comprising: pulverizing a coconut shell; carbonizing 
said coconut shell in an inert atmosphere to produce a coconut shell char; and 
heat-treating said coconut shell char at a temperature ranging from 900.degree. 
C. to 1,100.degree. C. in a steam gas atmosphere containing an inert gas 
selected from the group consisting of nitrogen, argon, and a combustion exhaust 
gas, wherein the content of steam in said steam gas atmosphere ranges from 30% 
by volume to 100% by volume, wherein said activated carbon has a BET specific 
surface area of 2000 m.sup.2/g to 2500 m.sup.2/g, and an average pore diameter 
of 1.95 nm (19.5 .ANG.) to 2.20 nm (22 .ANG.), wherein the pore volume of pores 
having a pore diameter, as calculated according to a !
 Cranston-Inkley method, of 5.0 nm (50 .ANG.) to 30.0 nm (300 .ANG.) is 0.05 
cm.sup.3/g to 0.15 cm.sup.3/g, wherein the amount of oxygen contained per g of 
said activated carbon is 1.8 mg to 8.1 mg, and wherein said activated carbon 
exhibits a spontaneous potential versus a lithium electrode of 2.85 V to 3.03 V 
in a non-aqueous electrolytic solution"

"The activated carbon of the invention is obtained by carbonizing coconut 
shell, then activating the carbonization product. Activating methods are 
roughly classified into a gas activation method and a chemical agent activation 
method. The gas activation method, which is also called physical activation in 
contrast to that the chemical agent activation is chemical activation, is an 
activation to produce activated carbon by bringing the carbonized raw material 
into contact with steam, carbonic acid gas, oxygen or other oxidizing gas at a 
high temperature to conduct reaction. The chemical agent activation method is a 
method of uniformly impregnating the raw material with an activating chemical 
agent, heating it in an inert gas atmosphere to cause dehydration and oxidation 
reaction of the chemical agent to thereby obtain activated carbon. As the 
chemical agents to be used, there are illustrated zinc chloride, phosphoric 
acid, sodium phosphate, calcium chloride, potassium sulfide,!
  potassium hydroxide, sodium hydroxide, potassium carbonate, sodium carbonate, 
sodium sulfate, potassium sulfate and calcium carbonate. "
