Provided is a heat medium heating unit comprising a plurality of flat heat exchange tubes, PTC heaters incorporated between flat tube portions, a heat exchanger pressing member that presses from one side the flat tubes and the PTC heaters against the inner surface of a casing, and a control board that is disposed above the heat exchanger pressing member and that controls the PTC heaters. A terminal extending upwards from an electrode plate directly connects to a terminal supports of the control board. On an inner surface of the casing, since a positioning means that engages with the terminal to position the terminal and the plate, the thermal contact resistance between the flat heat exchanger tubes and the PTC heaters is reduced.
