We have measured the magnetization of LaRu3Si2 to investigate the electronic states in the normal and superconducting states. LaRu3Si2 is a typical type II superconductor with the superconducting transition temperature T-s = 6.5 K. We estimated the lower critical field, upper critical field, coherence length, penetration depth and Ginzburg-Landau parameter at 2.0 and 4.2 K. We also derived these values at T = 0 K according to Ginzburg-Landau theory. In the normal state, the intrinsic magnetic susceptibility after subtracting the impurity part depends on temperature. The fact is considered to be due to a high density of states and a narrow band.
