Point contact spectroscopy experiments were performed on both single crystals Bi_{2}Sr_{2}CaCu_{2}O_{8+y} and BiSrCaCuO/Ag sintered material using gold tips. The spectra exhibit tunneling structure, which are interpreted in terms of the energy gap structure 2Δ = 58 meV at 4.2 K. We observed the strong Andreev reflection of the Au-BiSrCaCuO/Ag boundary.
