✦ Synopsis

Pressure effects on the electrical resistivity and thermoelectric power of La-Sr CuO-have been

studied.

The electrical resistivity decreases and thermoelectric power increases under pressure. The relative changes of these quantities are rather large in small x region and decreases with increasing x. Any distinct anomaly in the x-dependences of the pressure effect on the transport properties and the electronic specific heat coefficient T has not been observed at the superconducting-nonsuperconducting metallic phase boundary (x-.O.3), where the sign of the Hall coefficient changes.

This result suggests that the electronic state is continuous with the variation of x through the boundary.
