Abstract: A board production monitoring device for monitoring a production state of a board production device, including: a database section which consecutively obtains and stores production state data from the board production device; a transition graph display section which displays a transition graph showing a time-series change at least at a part of the production state data; a condition change input section which inputs condition change data which shows a change point of a production condition of the board production device and includes generation time information of the change point; and a condition change display section which displays at least the generation time information of the change point of the condition change data, at a time-series corresponding position in the transition graph, is provided.
