An analytical method has been developed for inverse problem of two-dimensional heat conduction by using Laplace transform technique. The inverse problem is solved only for simple boundary cases ; the first one is one unknown surface condition and the second is two unknown surface condition and the other surfaces are insulated in a finite rectangular body. The method first approximates the temperature changes obtained in a solid with a half polynomial power series of time and the Fourier series of eigen function. The expression for the surface temperature is explicitly obtained in the form of the power series of time and the Fourier series. The results calculated for some representative cases show that the temperature can be predicted at good agreement compared with the given surface condition while the estimate of surface heat flux becomes slightly worse than the surface temperature.
