Magnetocrystalline anisotropy constants of Fe_5Ge_3 were determined as K_1 =-5.1×10^6erg/cm^3,|K_3|=1.2x10^2erg/cm^3 for room temperature and K_1=-8.4×10^6erg/cm^3, |K_3|=1.6x10^2erg/cm^3 for liquid nitrogen nitrogen temperature by means of torque measurements. The temperature dependence of K_1 can be well interpreted by a one ion anisotropy model based on the Kanematsu's spin scheme and the molecular field approximation. Magnetostriction of the crystal at room temperature was studied by using strain gauges. Magnetostriction constants were determined as λ(001,100)=-20×10^<-6>,λ(001,001)=32x10^<-6> and λ(010,100)=6.7x10^<-6>. These values are qualitatively consistent with the one ion anisotropy model.
