摘要：
An electrode material is made of a tungsten oxide powder having an oxygen deficiency and a hexagonal tunnel structure along a b axis. The tungsten oxide powder is represented by WO 3-x , and preferably satisfies 0.1 ≤ x ≤ 0.3. A first peak intensity ratio I (010) /I (103) in an X-ray diffraction spectrum is preferably from 1 to 10.
