Study of resistivity and specific heat on CeCo_{12}B_6 compound was performed in a temperature range 2.5-300 K. The specific heat exhibits pronounced λ-type anomaly in the vicinity of the Curie temperature T_C. Using the Debye-Einstein model the following parameters were obtained: the Debye temperature θ_D = 185 K, coefficient of the electron specific heat γ_{el} = 115 mJ/mol K. The parabolic temperature dependence of resistivity ρ(T) = ρ_0 + A_ρT^2 was observed below T_C in agreement with ferromagnetic state. Comparison of dρ/dT(T) with C_M(T) allows to confirm their similar character, accordingly to theory of critical behavior.
