In order to improve heat transfer efficiency, this heat treatment furnace is equipped with a furnace body (10), a hearth (12), a blowing device (14), a wind-passing member (16), a heating device (18), and shelves (20). The furnace body (10) has openings (36) equipped with doors. The wind-passing member (16) has a tubular part and wind-guiding parts. The tubular part has an inlet and shelf-facing outflow ports.
