The heat medium heating device includes: a casing in which the flat heat exchange tubes 12 and the PTC heater 13 are stacked in multiple layers and incorporated; and a control substrate of the PTC heater 13 incorporated in the casing. In the heat medium heating device in which a terminal 25A extending from each electrode plate 25 of the PTC heater 13 is directly connected to a connection portion of the control substrate, the width dimension of the flat heat exchange tubes 12 is greater than a contact surface width in a direction in which the terminal 25A extends from each electrode plate 25 in the PTC element 24 of the PTC heater 13, and the electrode plates 25 and the flat heat exchange tubes 12 excluding the PTC element 24 are superimposed in the wide portion.
