A heat-treatment apparatus includes a casing, a loader which loads a workpiece to an inner part of the casing in order to apply a heat-treatment to the workpiece, and a canopy surface provided in the casing to cover the workpiece. The canopy surface includes a slope way with a sectional configuration where the canopy surface is cut on a plane vertical to a conveying direction of the workpiece inside the casing. The slope way includes a highest point and a downward inclined surface extending from the highest point to an outside of a zone between a perpendicular line extending from a left end of the workpiece and a perpendicular line extending from a right end of the workpiece.
