N2 - The effect of the disorder induced by the deuterated BEDT-TTF (d-BEDTTTF) molecule substitution on the superconductivity has been investigated in the quasi two dimensional organic superconductor κ-[(h-BEDT-TTF) 1-x(d-BEDT-TTF)x]2Cu(NCS)2. The scattering time τ obtained by the de Haas-van Alphen effect changes in the form of 1/τ x(1 - x), which is known as Nordheim relation. Although the scattering time takes minimum around x 0.5, the superconducting transition temperature Tc increases linearly with x. The relation between the scattering time and Tcis not simply explained by the nonmagnetic impurity effect in the unconventional superconductivity expected in this organic superconductor.
