We emphasize the effects of several factors on halo mass for our Galaxy, such as the disk thickness, the local surface density, and the shape of the rotation curve. By fitting the observed rotation curve of our Galaxy with the five-component model, we deduce a halo with a mass of 6.62×1011Modot within 50 kpc and a local density of 0.009Modotpc-3. It is found that the realistic Galaxy needs only about half of the halo mass that the Galaxy with an infinitesmally thin disk requires.
