The heat capacity of 3He in a silica aerogel with 98% porosity has been measured in both the normal and superfluid phases at a pressure of 20 bar with an adiabatic method. The results indicate a sharp peak at Tca = 1.8 mK with ΔCa/Ca = 1.0 ± 0.1. The value of ΔCa/Ca for superfluid 3He in aerogel is smaller than that for bulk 3He(= 1.8) directly indicating suppression of the amplitude of the order parameter.
