A stabilometer including: a platform a load detecting unit a time counting unit an arithmetic section and a biometric evaluating unit configured to evaluate postural stability of a test subject, wherein the arithmetic section includes a determining unit that determines when the test subject has placed one foot on the platform completely, and a determining unit that determines when the test subject with the one foot placed on the platform gets the other foot off of the ground, and the biometric evaluating unit evaluates the postural stability of the test subject from when the test subject has placed one foot on the platform completely to when the test subject with the one foot placed on the platform gets the other foot off of the ground on the basis of at least one of center of gravity locus data, load fluctuation data per unit time, and time data.
