A thermoelectric conversion substrate includes an insulating substrate and at least one thermoelectric conversion unit. The insulating substrate has a first surface and a second surface at both sides of the insulating substrate in a thickness direction. The at least one thermoelectric conversion unit is incorporated in the insulating substrate. The at least one thermoelectric conversion unit includes a first thermoelectric member, a second thermoelectric member, and a first electrode disposed on the first surface of the insulating substrate. The first thermoelectric member includes a first tubular member having insulation property and a first semiconductor filled in the first tubular member. The second thermoelectric member includes a second tubular member having insulation property and a second semiconductor filled in the second tubular member. The second semiconductor has carriers different from carriers of the first semiconductor. The first electrode electrically connects the first semiconductor of the first thermoelectric member to the second semiconductor of the second thermoelectric member.
