A thermoelectric generation module has a cooling surface formed on one of a front side and a rear side and a heating surface formed on the other thereof. The thermoelectric generation module includes: a plurality of thermoelectric elements; a pair of flexible boards holding the thermoelectric elements therebetween and respectively defining the cooling surface and the heating surface; a plurality of interelement electrodes respectively provided on opposed surfaces of the flexible boards and configured to electrically connect the thermoelectric elements to each other; a lead wire configured to be electrically connected to an interelement electrode to which a terminal element located at an end of an electrical arrangement is connected; and a reinforcing pattern interposed between the flexible boards and being closer to the drawn-out lead wire with respect to the terminal element.
