Low resistivity contacts to the bulk specimens of YBa
2Cu
3O
7-y with Ag have been developed. In order to obtain homogeneous mixtures of YBa
2Cu
3O
7-y and Ag we used Ag
2O powder, The contact resistivity of 0.19μΩ·cm
2 was obtained by annealing the specimen at 1, 100°C. The current versus voltage characteristic of the contact was found to be ohmic. The contact was made to the specimen which is exposed to air for 110 days; the contact resistivity after this period had elapsed was almost the same as the contact made to the fresh specimen. Using physical and chemical analysis it was found that all the Ag
2O in YBa
2Cu
3O
7-y was separated to Ag and that Ag existed in all voids.
