Specific heat C of κ-(BEDT–TTF)₂Cu(NCS)₂ was measured between T_c(10.4 K) and 3 K. An anomaly around T_c was observed. The specific heat data show unusual bending below T_c in the C⁄T versus T² plot. At the lowest temperatures, C obeyed the T³ law and no residual T-linear contribution was observed.
