Visible-region light measuring instrument and visible-region light measuring instrument manufacturing method

A visible-region light measuring instrument comprising:

• a first photodiode that is electrically connected between a first node and a first power supply node and has spectral sensitivity in the infrared region;
• and
• a second photodiode that is electrically connected between the first node and a second power supply node and whose spectral sensitivity in the visible region is greater than its spectral sensitivity in the infrared region,
• wherein:
• at least one of the first photodiode and the second photodiode comprises a plurality of photodiodes;
• when the first photodiode comprises a first plurality of photodiodes, the visible-region light measuring instrument has first fuses that control connections between the first plurality of photodiodes and at least one of the first node and the first power supply node;
• and
• when the second photodiode comprises a second plurality of photodiodes, the visible-region light measuring instrument has second fuses that control connections between the second plurality of photodiodes and at least one of the first node and the second power supply node.
