In a heat exchanger module of fired ceramic material produced from a stack of punched and laminated green ceramic cards, the stack comprises at least two cards. The cards have first cut-outs (1) which in stacked cards, form tubular channels (12) and second cut-outs (2 4, 7, 8) which are positioned around the first cut-outs (1) and which, in stacked cards, partially overlap with the second cut-outs (2, 4, 7) of adjacent cards. Channels (13) which lie in the plane of the cards and surround the tubular channels (12) are thus formed.
