Abstract: A thermoelectric power generation device includes a beam portion, a first leg portion, and a second leg portion formed integrally with a wiring substrate. The beam portion, the first leg portion, and the second leg portion are curved and deformed, and the first contact portion and the second contact portion integrally formed at the distal ends of the first leg portion and the second leg portion, respectively, are mounted in close contact with a heat source. The first leg portion and the second leg portion rise obliquely upward from the heat source, and the beam portion connected to the base ends of the first leg portion and the second leg portion is disposed above the heat source. Thermoelectric elements are mounted to the first leg portion and the second leg portion.

Abstract: A thermoelectric generator substrate includes: a flexible substrate including an insulating base material and a metal layer; and a cell substrate portion, wherein the cell substrate portion includes a strip-shaped first beam portion, a strip-shaped first leg portion whose one end is coupled to one end of the first beam portion and extends toward a center of the first beam portion, a strip-shaped second leg portion whose one end is coupled to the other end of the first beam portion and extends toward the center of the first beam portion, a first contact portion coupled to the other end of the first leg portion and in contact with a heat source, and a second contact portion coupled to the other end of the second leg portion and in contact with the heat source, and the first leg portion and the second leg portion are configured to deform and erect by widening an interval between the first contact portion and the second contact portion.
