Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent laser light and self-luminous light from interfering with each other, while obtaining the laser light for measuring a rugged shape on a furnace wall surface and the self-luminous light of the furnace wall at the same time, and to broaden measurable range in a direction vertical to the furnace wall surface and irradiation range of the laser light.SOLUTION: The furnace wall shape measuring device comprises: a slit laser light source 4 for emitting slit laser light; a mirror 5 for laser light for reflecting the laser light and irradiating a furnace wall surface with the laser light through a window 2; a mirror 6 for imaging for reflecting reflected light of the furnace wall surface by irradiation of the laser light and self-luminous light emitted by the furnace wall surface, which are incident into inside of a heat insulating protective box 3 through the window 2; and an imaging unit 8 for imaging the self-luminous light and the reflected light reflected from the mirror 6 for imaging through an optical filter 7; all of which are arranged inside of the heat insulating protective box 3 having the slit shaped window 2.
