In this study, we attempted to measure human well-being by psychological needs satisfaction. We asked questionsregarding needs satisfaction level for 35-needs items. The results of an exploratory factor analysis indicated a three-factorstructure of needs satisfaction ; Factor1: personality-needs, Factor2 : relationship-needs, and Factor3 : sociality-needs.Each of these three factors showed statistically sufficient internal consistency. The results showed that all these factorswere significantly correlated with Satisfaction with Life Scale: SWLS, Interdependent Happiness Scale: IHS, and SelfesteemScale（over r =.30）. Additionally, we did SEM（ Structural Equation Model analysis） in order to check on the constructionthat makes up human well-being（ χ2=4.62, p<.09 ; GFI=.99, AGFI=.92, CFI=.98, RMSEA=.08）. Personality-needsfactor had a strong positive effect on HIS（ β=.64, p<.001）, but relationship-needs factor had a negative effect on IHS（ β=-.16, p<.10）. In addition, sociality-needs factor had a strong positive effect on self-esteem scale（ β=.40, p<.001）. Finally wediscuss about the reliability, the validity, and the usefulness of the“ psychological needs satisfaction” scale.
