We studied electrical resistivity of single crystals of an oxide superconductor Sr2RuO4 under hydrostatic pressure up to 12 kbar. The midpoint Tc decreases at the rate of 3%/kbar. Anomalous increase of resistivity along the c axis is observed at room temperature with increasing pressure, whereas that in the ab plane decreased with pressure as normally expected.
