Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an electrode material which enables the formation of a power storage device low in internal resistance at a low temperature and less in quantity of gas generated when it is held in a state of being charged.SOLUTION: An electrode material comprises a carbon material. When performing a thermogravimetric analysis on the electrode material in an air stream of 100 ml/min at a temperature rise of 5°C/min, the temperature when the weight of the material decrease by 20% of the weight before the rise in temperature is 650°C or below.SELECTED DRAWING: None 【課題】低温での内部抵抗が低く、しかも充電状態で保持した際に発生するガス量が少ない蓄電デバイスを形成することができる電極材料を提供すること。【解決手段】炭素材料を含有し、１００ｍｌ／分の空気気流中、昇温速度５℃／分で熱重量分析した際、昇温前に対して２０％重量減少する温度が６５０℃以下である電極材料。【選択図】なし
