A method for measuring thermal conductivity of a material comprises the following steps: A heat pulse is applied to a front side of the material. The resulting time- dependent two-dimensional temperature field of the front side of the material is detected using an infrared detector. An isotherm is identified in the temperature field. First and second thermal conductivities of the material in first and second directions of the material are calculated on the basis of the shape of the isotherm and on the basis of first and second temperatures detected at one point of the front side of the material at two points in time.
