Abstract
The invention provides a pyranometer with a fast response time, a reduced offset amount, and reduced impacts from harsh outside environment and an enhanced long-term stability, as well as an excellent cosine response. The pyranometer has: a silicon-based thermopile sensor, which is sealed airtight in a CAN package and positioned opposed to the receiving surface of the thermopile sensor; and diffusing member that is positioned so as to be opposed to a receiving surface of the thermopile.
