Thermoelectric conversion module

A thermoelectric conversion module comprising:

• a long support having flexibility and insulating properties;
• a plurality of first metal layers formed on one surface of the support at intervals in a longitudinal direction of the support;
• a plurality of thermoelectric conversion layers formed on the same surface of the support as the surface provided with the first metal layers at intervals in the longitudinal direction of the support;
• a connection electrode for connecting the thermoelectric conversion layers adjacent in the longitudinal direction of the support on the same surface of the support as the surface provided with the first metal layers;
• and
• a second metal layer formed on a surface of the support opposite to the surface on which the first metal layer is formed,
• wherein the first metal layer has a first low rigidity portion having rigidity lower than rigidity of other regions and extending in a width direction of the support,
• the second metal layer has a second low rigidity portion having rigidity lower than rigidity of other regions and extending in the width direction of the support,
• the second low rigidity portions of the second metal layer are formed at the same positions as each first low rigidity portion of the plurality of first metal layers in the longitudinal direction of the support, and
• the support is alternately bent into a mountain fold and a valley fold at the first low rigidity portions of the plurality of first metal layers and the second low rigidity portions of the second metal layer in the longitudinal direction.
