Abstract

A sintering apparatus comprising a flimace core tube having an opening in a top end through which the soot deposition body is inserted, and having atmospheric gas introduced therein from below and expelled upward; a shaft from which the soot deposition body hangs; a lid that has the shaft inserted therethrough and can cover the opening; a heating furnace that heats the soot deposition body; an internal lid in a top portion of the flimace core tube that divides the top portion of the furnace core tube into an upper region and a lower region; and a gas flow path that connects the two regions to each other and has the atmospheric gas flow therethrough. Total cross-sectional area, relative to movement direction of the atmospheric gas, of the gas flow path is less than cross-sectional area, relative to movement direction of the atmospheric gas, of the furnace core tube.
