PROBLEM TO BE SOLVED: To provide a device for easily measuring a parameter to be used as an index of a gas adsorption rate in adsorbent. SOLUTION: The adsorption rate measuring device is provided with a pressure vessel with adsorbent having an adsorbent housing means housing the adsorbent in an interior, a pressure producing means applying pressure by measuring object gas to the pressure vessel with adsorbent, and a pressure feeding means feeding the measuring object gas pressure produced by the pressure producing means to the pressure vessel with adsorbent. It is characterized by that it is provided with a gas flow rate measuring means measuring a time series change of flow rate of the measurement object gas flowing between the pressure vessel with adsorbent and the pressure producing means, and a calculating means calculating the adsorption rate of the adsorbent from the gas flow rate measured by the gas flow rate measuring means.
