Abstract:
An electric heater device (10) comprises a plurality of pipelines (21), and heating elements (30). The plurality of pipelines are layered as a heat exchange section (20) between an inflow pipe (70) into which water flows and a discharge pipe (71) from which the water flows out, the water flowing in a distributed manner within the pipelines, and a prescribed gap being maintained therebetween. The heating elements are disposed in the gaps between the plurality of pipelines, and emit heat on the basis of the supply of power. The electric heater device furthermore comprises a case (40) and electronic components (81, 82, 83). The case internally houses the heat exchange unit and the heating elements, and has a contact part (44) that comes into contact so as to be capable of conducting heat with the pipelines at the end furthest in the lamination direction among the plurality of pipelines of the heat exchange unit. The electronic components are provided so as to be capable of conducting heat with the contact part of the case.
