ABSTRACT:
Disclosed is a thermopile improved in its measurement sensitivity and manufacturing cost, which comprises a pillar-shaped substrate having a side extending in the parallel direction to an incident light to be measured so as not to be irradiated with the incident light, and first and second thermoelectric material layers arranged alternately on the side of the pillar-shaped substrate along the extending direction of the side of said pillar-shaped substrate. The first thermoelectric material layers and second thermoelectric material layers are connected each other in series such that one end of each first thermoelectric material is connected to one end of each second thermoelectric material at an incident-light side end portion of the side of said pillar-shaped substrate in the extending direction thereof and another end of each first thermoelectric material is connected to another end of each second thermoelectric material at the other end portion of the side of said pillar-shaped substrate opposite to the incident-light-side end portion in the extending direction thereof.
