To provide an emissivity measuring apparatus which measures the emissivity of a sample accurately by a simple apparatus structure.

The apparatus includes a handle 18 which includes an electric furnace 13 fixed on its one end for heating the sample 4 and of which the other end pivots about a fulcrum 20. When the handle 18 has pivoted from a heating position A in which the electric furnace 13 is fitted into the sample 4 to a standby position B, the center line X of the electric furnace 13 is spaced with an inclination angle with respect to the sample 4.
