To suitably support a heat insulation material arranged at the inside of a furnace when carrier rollers pass through the heat insulation material.SOLUTION: A heat treatment furnace heat-treats an object to be treated. The heat treatment furnace comprises: a furnace body provided with a heat treatment space for heat-treating the object to be treated; a heat insulation material covering the inner surface of the furnace body; a plurality of carrier rollers arranged at the inside of the furnace body, in which the edge parts pass through the heat insulation material and the furnace body, and arranged at the outside of the furnace body; a driving device for driving the plurality of carrier rollers; and a support member arranged at the inside of the heat insulation material and having a mechanical strength higher than that of the heat insulation material. The support member includes a through hole passing through in the axial direction of the carrier rollers. The carrier rollers are arranged at the through hole.SELE
