When the $d_{x^2-y^2}$-wave pairing is suppressed by Zn-doping in$YBa_2Cu_3O_{7-\delta}$ some of the Andreev reflection spectra were found to besimilar to the s-wave spectra of conventional superconductors. The energy gapis rather reproducible (2.3-3.0meV). It is suppressed by low magnetic field($H_C^{PC}=120-270mT$) in great contrast to the d-wave spectra ($H_C^{PC}>3T$)with the similar order of the gap value. We suppose that the s-wave pairingoccurs near the Zn-impurities.
