Abstract
An apparatus for accurately measuring carbon dioxide partial pressure even if the apparatus is disposed in an environment at a high ambient water pressure, such as in a deep sea environment. A through hole that penetrates a body portion is formed in the body portion. The body portion is connected to a light source unit and a light receiving element unit. A signal line is disposed to pass through the through hole formed in the body portion. The signal line electrically connects between an amplifier substrate of the light receiving element unit and a CPU substrate of the light source unit to transfer the detection result amplified by the amplifier substrate.
