An insulating glass pane (1) has at least two glass plates (10, 12) which are spaced apart from one another, and an edge joining strip (14) which surrounds and joins together the glass plates (10, 12) in the region of their edges. The edge joining strip (14) seals and delimits an insulating cavity (16) which is located between the glass plates (10, 12) and which is filled with a fill gas which is not air. A sensor (18) is provided in the insulating cavity (16) of the insulating glass pane (1), which sensor reacts and gives a signal if the composition of the fill gas changes.
