PROBLEM TO BE SOLVED: To provide an alcohol measurement device capable of smoothly measuring an alcohol concentration contained in expiration.SOLUTION: An alcohol measurement device includes: a mouthpiece 11 that is held in the mouth of a measured person and to which the expiration of the measured person is blown in; an alcohol detection part 13 for measuring an alcohol concentration contained in the expiration; a flow rate detection part 12 for measuring the flow rate of the expiration; an operation part 21 for determining whether the flow rate of the expiration during the measurement of the alcohol concentration by the alcohol detection part 13 satisfies a predetermined condition or not on the basis of the output of the flow rate detection part 12; and a vibration part 24 for generating a vibration. The operation part 21 outputs a control signal to control a timing for the generation of the vibration by the vibration part 24 and a period for the generation of the vibration on the basis of the result of the determination whether the flow rate of the expiration satisfies the predetermined condition or not. |
