We have revealed that the high-T c Cu-oxide superconductors show a large variety of the pressure coefficients of T c. These characteristic features are clearly distinguishable from conventional BCS superconductors. The results are compared with normal metallic superconductors and discussed assuming the BCS theory. It is deduced that the McMillan-Hopfield parameter is the most significant single parameter in understanding the origin of the systematic pressure dependence of T c.
