Measurements of electrical resistivity (37 mK:< T<780 K for CeB5), magneto-resistivity (f<100k0e) and Hall resistivity (ff<150k0e, 4.2K'<I$53K)have been done for single crystalline samples of Ce.La.=.B5 (0.03$.v@1). Atvery low temperatures, the T' law of resistivity is confirmed. A kind of uni-versality for A/y'zx is found even for magnetically ordered CeB5. The coo-centration dependence of residual resistivity shows that an interaction effectbetween Kondo states appears sharply around ,v=0.1. The interaction is weakfor x<0.1 and does not vary so much for 0.1:<,v<1. The Hall resistivity isproportional to magnetic field up to 150 k0e and is independent of the fern-perature down to 4.2 K. The real value of the Kondo temperature is evaluated.
