We report on the frequency stabilization of a diode laser, in which the long- and short-term stabilities are simultaneously improved. We use an external cavity whose resonance frequency is locked to the center of a Doppler-free spectrum of the ^<85>Rb-D_2 line without direct laser frequency modulation. The obtained linewidth of the diode laser is less than T100 kHz and the long-term stability (trackability) estimated from the variation of the error signal is between 2×10^<-12> and 2×10^<-14> at the averaging time т between 100 ms and 100 s. We also propose a conventional method of stabilization of the magnetic field at the Rb cell used for the frequency stabilization.
