| 1. A layered ruthenic acid intercalation compound comprising a layered structure of ruthenic acid nanosheets, each ruthenic
acid nanosheet having a thickness of not more than 1 nm. represented by the formula (1): [RuO2+0.5x]x−, wherein 0<x<1, and alkylammonium,
said layered ruthenic acid compound having an X-ray diffraction peak intensity at a (00L) plane (L=1 to n when 0≤0(CuKα)≤90°,
n is determined depending on a basal interplanar spacing and 5≤n≤35).
