PROBLEM TO BE SOLVED: To provide a reflow furnace monitoring device capable of grasping an accumulation flux amount during operation of a reflow furnace.SOLUTION: A reflow furnace monitoring device has a flux content storage section, a print solder paste amount acquisition section, a print flux amount calculation section and an accumulation flux amount calculation section. The flux content storage section stores a flux content of a solder that is to be subjected to reflow by a reflow furnace. The print solder paste amount acquisition section acquires a print solder paste amount printed on a workpiece before reflow. The print flux amount calculation section calculates a print flux amount printed on the workpiece based on the flux content and the print solder paste amount. The accumulation flux amount calculation section calculates the accumulation flux amount accumulated in the reflow furnace from a predetermined initial state based on specification of the reflow furnace, the print flux amount and the reflow execution history.SELECTED DRAWING: Figure 1
