Thermal diffusivity of three free-standing PCVD diamond films have been measured by ac calorimetric method. The thermal diffusivity ranges from 0.28 cm{sup 2}/s to 4.44 cm{sup 2}/s under a variety of the methane concentration from 0.2 to 1.0%(vol). The systematic errors such as heat loss, non-one-dimensional heat conduction, edge reflection are considered. For the diamond sample, the edge reflection is not able to be negligible and it is analytically corrected.
