Abstract

A heating device is provided with plates stacked one on top of another. At least one first fluid channel is formed in a fluid-tight manner between a first plate package with a first and a second plate. An electrical heating element is arranged between a first plate of the first plate package and an additional plate. The electrical heating element is accommodated between the two plates in a sealed manner and is electrically insulated, wherein an inlet-side and an outlet side fluid connection of the first fluid channel is arranged on the second plate of the first plate package. The electrical heating element has a connection device for electrical contacting, which is connected to the electrical heating element and protrudes through a window in the second plate of the first plate package, wherein the fluid connections and the window are arranged adjacent to opposing lateral edges of the second plate.
