The disclosed device is provided with: a first heat-medium circulation box (A) and a second heat-medium circulation box (B) that are in close contact with two sides of a PTC heater (40), respectively, and are joined to each other in a liquid-tight manner; an electrical-component cooling wall section (26); and electrical components (23a) affixed to the electrical-component cooling wall section (26). Heat-medium circulation channels (33 and 54) are formed inside the first and second heat-medium circulation boxes (A and B). The electrical-component cooling wall section (26) is provided for example in the first heat-medium circulation box (A), adjacent to that heat-medium circulation channel (33). On the surface of the electrical-component cooling wall section (26) facing said heat-medium circulation channel (33), protrusions (26a) that extend into said heat-medium circulation channel (33) are formed at positions precisely opposite the positions where the electrical components (23a) are seated. Said protrusions (26a) also serve as fastening bosses for fastening members (25b) that fasten the electrical components (23a) to the electrical-component cooling wall section (26).
