Provided is a heating device which is capable of smoothening flow of a heat medium while reducing a processing time of a case. A heating deviceis constituted of a caseincluding therein a flow paththrough which a heat medium flows, and electric heating wire heatersarranged in the flow pathof the caseto heat the heat medium. The caseis constituted of a first case sectionand a second case sectioneach of which has at least one opened surface and which are connected to each other in a state where respective openingsA andA are made to abut on each other. The respective case sectionsandare formed by casting of a metal.

Heating device and method for manufacturing heating device

Provided is a heating device which makes it possible to effectively perform heat exchange between a heating element and a heat medium without increasing the number of components, and further to eliminate air retention and increase of a pressure loss. A heating deviceis constituted of a caseincluding therein a flow paththrough which a heat medium flows, and an electric heating wire heaterdisposed in the flow path of the case to heat the heat medium. The case comprises a first case sectionand a second case sectioneach of which has at least one opened surface and which are connected to each other in a state where respective openings are made to abut on each other, and a plate-like gasketwhich is interposed between abutment portions of the first case section and the second case section, and seals a space between both the case sections, and the gasket controls the flow of the heat medium in the flow path.
