Abstract(in English)	Relativistic effect on the quasi-zenith satellites appears in (a) clock delation, (b) signal propagation delay, and (c) correction to the acceleration. Especially, for quasi-zenith satellites with elliptical orbits, effect on clock delation appears definitely since relativistic effect cause the periodic change whose amplitude is proportional to eccentricity and the square root of semimajor axis. This amplitude is 40 ～ 126 times larger than that for GPS. Signal propagation delay cause periodic change about 0-1.5 [cm]. Perturbation due to the relativistic effect is an order of 10^<-10> [m/s^2]. It is about 1% of solar radiation pressure.
