ABSTRACT:
A heat treatment apparatus includes a heating furnace including a tunnel-shaped heating space for heating an object to be heated, the heating space having an inlet port and an outlet port formed at both ends thereof; a transporting unit transporting the object to the outlet port when the object is brought into the heating space through the inlet port; a heating unit heating the object that is being transported; and a gas-flow generation unit forming a gas flow that flows in a transporting direction of the object in the heating space, wherein the heating space has a cross-section orthogonal to the transporting direction of the object, the cross-section is changed in area along the transporting direction of the object.
