We investigate the clustering properties of 2600 Lyman break galaxies (LBGs) at z=3.5-5.2 in two large blank fields, the Subaru Deep Field and the Subaru/XMM-Newton Deep Field (600 arcmin² each). The angular correlation functions of these LBGs show a clear clustering at both z≃4 and 5. The correlation lengths are r₀=4.1^+0.2_–0.2and 5.9^+1.3_–1.7h^–1₁₀₀ Mpc (r₀=5.1^+1.0_–1.1and 5.9^+1.3_–1.7h^–1₁₀₀Mpc) for all the detected LBGs (for L≳L^* LBGs) at z≃4 and 5, respectively. These correlation lengths correspond to galaxy-dark matter biases of b_g=2.9^+0.1_–0.1and 4.6^+0.9_–1.2(b_g=3.5^+0.6_–0.7and 4.6^+0.9_–1.2) for all the detected LBGs (for L≳L^* LBGs) at z≃4 and 5, respectively. These results, combined with estimates for z≃3 LBGs in the literature, show that the correlation length of L≳L^* LBGs is almost constant, ∼5 h^–1₁₀₀Mpc, over z≃3-5, while the bias monotonically increases with redshift at z≳3. We also find that for LBGs at z≃4 the clustering amplitude increases with UV-continuum luminosity and with the amount of dust extinction. We estimate the mass of dark halos hosting various kinds of high-z galaxies, including LBGs, with the analytic model given by Sheth & Tormen. We find that the typical mass of dark halos hosting L≳L^* LBGs is about 1x10¹² h^–1₇₀M_☉over z≃3-5, which is comparable to that of the Milky Way. A single dark halo with ∼10¹² h^–1₇₀M_☉is found to host 0.1-0.3 LBGs on average but about four K-band-selected galaxies.
