We report on the results of the 73Ge-NQR measurements for MPt4Ge12 (M = Sr, Ba) to clarify the microscopic electronic states and the relationship between superconductivity and rattling. In the normal state, 1/T1 is proportional to temperature, showing a Korringa relation 1/T1T = 0.020 and 0.016 (sK)-1 for SrPt4Ge12 and BaPt4Ge12, respectively. Also, in the superconducting state, 1/T1 shows a distinct coherence peak just below TC, which suggests a conventional BCS superconductor.
