The present invention relates to a composite pane (100) with a capacitive switching region (10), comprising at least: - a substrate (1), - at least one first intermediate layer (2) which is joined extensively to the substrate (1), - at least one second intermediate layer (3, 3') which is joined extensively to the first intermediate layer (2), and - an outer pane (4) which is joined extensively to the second intermediate layer (3, 3'), wherein a carrier film (5) having an electrically conductive layer (6) is arranged at least in sections between the first intermediate layer (2) and the second intermediate layer (3, 3'), a capacitive switching region (10) is separated electrically from the electrically conductive layer (6) by at least one coating-free dividing line (7), the capacitive switching region (10) has a contact region (11), a supply region (12) and a connection region (13), the supply region (12) electrically connects the contact region (11) to the connection region (13) and the connection region (13) is electrically connectable to sensor electronics (14), and the surface capacitance (cI) between the contact region (11) and the external surface (IV) of the substrate (1) is greater than the surface capacitance (cA) between the contact region (11) and the external surface (I) of the outer pane (4).
