1. A thermoelectric transducer comprising:
a substrate;
a thermoelectric film on the substrate;
a first electrode on the substrate; and
a second electrode on the substrate, the second electrode being different from the first electrode in work function,
wherein the first electrode and the second electrode are in contact with a same side of the thermoelectric film,
wherein the first electrode includes a first connection terminal part for supplying an output voltage outside of the substrate,
wherein the second electrode includes a second connection terminal part for supplying an output voltage outside of the substrate,
wherein the first connection terminal part and the second connection terminal part are distant from the thermoelectric film when viewed planarly,
wherein the thermoelectric film is a first thermoelectric film,
wherein the thermoelectric transducer further comprises:
a first island-like thermoelectric film located on the same layer as the first thermoelectric film but distant from the first thermoelectric film; and
a second island-like thermoelectric film located on the same layer as the first thermoelectric film but distant from the first thermoelectric film,
wherein the first thermoelectric film is located between the substrate and both of the first electrode and the second electrode, and
wherein the first connection terminal part and the second connection terminal part are laminated in contact with the first island-like thermoelectric film and the second island-like thermoelectric film, respectively, and
wherein an outer edge of the thermoelectric film is located inner than an outer edge of the substrate.
