Abstract
Determination about presence/absence of alcohol in the body is made accurately.A frequency dynamic information processing means 610 which obtains a tendency of time-series fluctuation regarding a frequency of a pulse wave of a back portion of a person detected by an air pack and an alcohol-drinking determining means 650 which determines an alcohol-drinking state when a tendency of a time-series fluctuation regarding the frequency obtained by the frequency dynamic information processing means 610 is separated from a tendency of time-series fluctuation regarding the frequency at a non-drinking state are provided. Since determination about whether or not a person is in an alcohol-drinking state is made according to comparison with time-series fluctuation regarding the frequency at a non-drinking time, where the determination is made using not only frequency analysis of the frequency of a pulse wave changing according to the physical condition of the person but also the time-series fluctuation thereof, determination about presence/absence of alcohol drinking can be made more accurately as compared with the conventional method.
