When temperature suddenly changes an ablator material inside, a predicted in-depth temperature using the thermal conductivity that measured in the steady state, it does not accord it to measured value strictly. One of these reasons is because an input energy to a material is spent by the conductive heat transfer, the increase of the internal energy and the work of the thermodynamics. After heating an ablator of specific weight approximately 0.3, a temperature rise of an early period of heating was slow. This means a possibility that an energy input was spent by these. An accurate prediction of the in-depth temperature is important to a thickness design of ablator. This manuscript shows a necessity of a manifestation of the process of the input energy expenditure
