PROBLEMS TO BE SOLVED: A finger arterial elasticity measuring program, a finger arterial elasticity measuring device and a finger arterial elasticity measuring method are provided for making it possible to measure an elasticity index of a finger artery in accordance with a pulse wave of a finger artery without measuring a blood pressure in evaluating the elasticity of the finger artery related to the degree of arterial sclerosis in an easy and least expensive manner. MEANS FOR SOLVING THE PROBLEMS: A computer functioning by a finger arterial elasticity measuring program includes a pulse wave data memory unit 42, a cuff pressure data memory unit 43, a normalized pulse volume (NPV) calculating unit 52 for dividing an amplitude (DeltaI) of an alternate component of a pulse wave by an average value of direct components (I) to calculate NPV, a relative cuff pressure (Pr) calculating unit 53 for calculating a difference between a cuff pressure at the maximum amplitude of the pulse wave and each cuff pressure as Pr, an FEI calculating unit 54 for calculating a linear regression slope (n) of the following expression (1) as an elasticity index of a finger artery: ln(NPV)=ln(bn)-n.Pr . . . (1) where b is a constant.
