Thermoelectric module

A thermoelectric module, comprising:

• a first support substrate comprising a first insulating substrate attached to a first metal plate;
• a second support substrate comprising a second insulating substrate attached to a second metal plate, the first insulating substrate and the second insulating substrate each having a first surface wherein the first surface of the first insulating substrate faces the first surface of the second insulating substrate in a plan view;
• first wiring conductors located on the first surface of the first insulating substrate, and second wiring conductors located on the first surface of the second insulating substrate;
• a plurality of thermoelectric elements located between the first surfaces of the first insulating substrate and the first surface of the second insulating substrate, and electrically connected through the first wiring conductors and the second wiring conductors;
• wherein the first support substrate or the second support substrate comprises a first protrusion in the plan view, the first protrusion comprising a metal pattern that is electrically isolated from any one of the wiring conductors on either one of the first support substrate or the second support substrate of which the first protrusion protrudes, and
• wherein the protrusion comprises an angled outer side and an angled inner side that decrease a width of the first protrusion as the first protrusion extends in a direction away from the plurality of thermoelectric elements .
