Using fourth-sound techniques, we have measured the depression of the superfluid fraction of /sup 3/He confined in small pores of packed powder over wide temperature (0.2<1) and pressure (0.5<20 bars) ranges. From the analysis of the data we determine the magnitude and the pressure dependence of the healing length. The healing length decreases from 520 A at 0.5 bar to 200 A at 20 bars. The values are in fair agreement with those expected from the BCS expression.
