## Abstract

A thermoelectric power generation unit includes: a bottom plate and a heat exchange member which are made of a thermal conductor; a thermoelectric power generation module and a spacer which are interposed between the bottom plate and the heat exchange member; and a side wall provided to cover a gap between the bottom plate and the heat exchange member. Moreover, a circuit board on which a circuit that is driven by electric power obtained by the thermoelectric power generation module is mounted is stored in a space surrounded by the bottom plate, the heat exchange member, and the side wall.

## Claims

### Claim 1

A thermoelectric power generation unit comprising:
a heat exchange member;
a bottom plate made of a thermal conductor;
a thermoelectric power generation module interposed between the bottom plate and the heat exchange member;
a side wall provided to cover a gap between the bottom plate and the heat exchange member; and
a circuit board disposed in a space partitioned by the heat exchange member, the bottom plate, and the side wall and having a circuit mounted thereon, the circuit being driven by electric power obtained by the thermoelectric power generation module.

### Claim 2 (depends on 1)

The thermoelectric power generation unit according to claim 1, wherein the bottom plate is thermally separated from the heat exchange member.

### Claim 3 (depends on 2)

The thermoelectric power generation unit according to claim 2, wherein the bottom plate is joined to the heat exchange member via the side wall and a sealing member having heat insulation properties.

### Claim 4 (depends on 1)

The thermoelectric power generation unit according to claim 1, further comprising:
a spacer made of a thermal conductor and laminated with the thermoelectric power generation module,
wherein the spacer is provided in the space.

### Claim 5 (depends on 1)

The thermoelectric power generation unit according to claim 1, further comprising:
a spacer made of a thermal conductor and laminated with the thermoelectric power generation module,
wherein a part of the spacer protrudes from the bottom plate so as to be provided outside the space.

### Claim 6 (depends on 1)

The thermoelectric power generation unit according to claim 1, wherein:
the thermoelectric power generation module is disposed at the center of the bottom plate;
the circuit board has substantially the same external dimensions as the bottom plate; and
a cutout is provided in the circuit board, the thermoelectric power generation module being disposed in the cutout.
