Abstract
This infrared ray detection element has a diode part that includes serially connected first and second p-n junction diodes. The diode part has: n-type and p-type first regions in a well shape that are adjacent to each other; a p-type second region that constitutes a first p-n junction diode with the n-type first region; and an n-type second region that constitutes a second p-n junction diode with the p-type first region. The n-type and p-type first regions are respectively provided with n-type and p-type third regions that electrically connect the first p-n junction diode and the second p-n junction diode via a conductive material. The n-type first region has a p-type fourth region provided between the p-type first region and the p-type second region. The p-type first region has an n-type fourth region provided between the n-type first region and the n-type second region.
