To provide an antimonic acid film having an excellent conductivity and a high response to humidity, and useful as a high-performance humidity sensor, a hydrogen gas sensor or a hydrogen fuel cell, the present invention provides an antimonic acid film comprising single crystals of cubic antimonic acid dispersed in amorphous antimonic acid by causing metallic antimony or an oxygen-containing compound thereof to react with hydrogen peroxide using the resultant reaction solution as the raw material, and forming a film on an insulated substrate.
