To provide a heat medium heating device having multiple rod-shaped heat generators are housed in a casing and to improve the circulation resistance of heating flow passages which are aligned in parallel with each other along the rod-shaped heat generators and a circulation flow passage which provides communication between the heating flow passages.SOLUTION: A heat medium heating device comprises a plurality of rod-shaped heat generators which are aligned in parallel with each other, and a casing in which the plurality of rod-shaped heat generators are accommodated. The casing comprises a plurality of heating flow passages through which a heat medium circulates along the rod-shaped heat generators, and a communication flow passage which provides communication between the plurality of heating flow passages. The communication flow passage has a flow passage expansion portion which expands a flow passage width for the heat medium on a side opposite to an extension direction of the heating flow passages.SELECTED DRAWING: Figure 2 【課題】複数の棒状発熱体が筐体に収容された熱媒体加熱装置において、棒状発熱体に沿って並列された加熱流路とこれを連通させる連通流路の流通抵抗を改善し、複数の加熱流路における熱媒体の流れの不均一さを解消する。【解決手段】熱媒体加熱装置は、並列配置した複数の棒状発熱体と、複数の棒状発熱体が収容された筐体とを備え、筐体が、棒状発熱体に沿って熱媒体を流通させる複数の加熱流路と複数の加熱流路を連通させる連通流路を備える熱媒媒体加熱装置であって、連通流路は、前記加熱流路の延長方向とは逆側に熱媒体の流路幅を拡大させる流路拡大部を有する。【選択図】図２
