The onset of a charge density wave has been studied by resistivity measurements in 2H-TaS2 up to 33 kbar. The pressure coefficient of T CDW is [FORMULA] at ambient pressure. A larger pressure dependence occurs at higher pressure and suggests that the normal metallic state of 2H-TaS2 may be stable down to 0 K above 43 kbar. The relation between a CDW state and the pressure enhanced superconductivity is discussed
