Abstract: A measurement method measures an amount of substance of an analyte in a sample fluid passing through a perforated structure having a pair of principal surfaces opposed to each other and having a plurality of cavity portions extending through both of the principal surfaces. An elapsed time from a time when the sample fluid begins passing through the perforated structure or a predetermined time thereafter to a time when a characteristic value of the perforated structure reaches a predetermined threshold. The elapsed time is used to determine the amount (the concentration) of substance of the analyte.
