Abstract: The device includes heat transfer portions, each of which is configured to thermally connect: one electrode provided on one side of a hot junction side and a cold junction side of each thermoelectric conversion element; and a heat transfer member. A base material has recesses on a second surface side, the recesses being provided so as to be recessed in a range of a region which overlaps with interspaces between other electrodes provided on other side of the hot junction side and the cold junction side of the each thermoelectric conversion element in a plan view. A low thermal expansion layer is provided on a surface side of each of the thermoelectric conversion element facing the heat transfer member or a high thermal expansion layer is provided on a surface side of each of the thermoelectric conversion elements facing the recess.

Abstract: A gas sensor includes a base member, a first insulating film, a second insulating film, a heater section, a flat section, and a gas detection section. The base member is provided with a cavity. The first insulating film includes beam portions connected to a peripheral portion of the cavity of the base member and a first-insulating-film membrane portion held over the cavity by the beam portions. The second insulating film is laminated on an upper side of the first insulating film. The heater section is provided on an upper side of the first-insulating-film membrane portion. The flat section is provided between the first-insulating-film membrane portion and the second insulating film and disposed closer to a center of the first-insulating-film membrane portion than the heater section and forms a flat surface. The gas detection section is disposed on at least the second insulating film over the flat section.
