PROBLEM TO BE SOLVED: To provide a reflow furnace in which, in order to prevent a gasified flux from depositing and solidifying on a motor rotary shaft for rotating fans disposed in a preheating zone, a main heating zone, and a cooling zone, the gasified flux is collected in a flowable liquid state before the solidification in an efficient and reliable manner. SOLUTION: A drain part 20 constituting a flux collection device 10A is provided on a side opposite to a fan of a motor base 16 and in a peripheral part of a rotary shaft 14. The face opposite to a fan of a drain part 20 constitutes an inclined face 20a that is inclined from a plane position of the motor base 16 toward a discharge port 46 provided on the backside of the motor base 16. The flux collected in a center part of the motor base 16 by the rotary drive of the fan flows into a drain part 20 provided in a center part of the motor base 16, flows along the inclined face 20a, is passed from the drain part 20 through the discharge port 46, a drain pipe, and a pipe 48 and is received in a collection container 34.
