Point contact spectroscopy results are presented on the electron underdoped Ba(Fe_{0.96}Co_{0.04})_2As_2 single crystals. Two superconducting energy gaps with coupling values 2 Δ_1 ∿ kT_{c} ≈ 2.55 and 2 Δ_2 ∿ kT_{c} ≈ 11 at T_{c} = 15.5 K have been observed in the point contact spectra. The temperature dependence of the normal state background of the point contact spectra observed between T_{c} and T_{N} indicates antiferromagnetic origin of the V-shaped minimum at zero bias.
