A hot water heating apparatus for an electric vehicle and a hybrid vehicle has a compact heat source apparatus not requiring a wide space for setting. A communication pipe, in which water as a heat medium flows, and an electric heater are embedded in a heat conductor metal in proximity in a row arrangement to form a flat-shaped heat conductor. A heat source apparatus is constructed by stacking multiple flat-shaped heat conductors while the communication pipes are connected to each other in series. Further, the communication pipe and the electric heater are embedded in the heat conductor metal in proximity in a row arrangement, and the communication pipes are connected in series. Therefore, water flowing in the communication pipes is rapidly heated, and heating efficiency is extremely high.
