Abstract
An optical sensor is provided, in which members forming an optical path can be reliably supported without blocking the optical path extending from a light source to a light receiver. An optical sensor includes a light source configured to emit light, and a light receiver configured to receive the light emitted from the light source. An optical path extending from the light source to the light receiver extends through an oil infiltrating space into which oil infiltrates. The optical sensor further includes: a substrate on which the light source is mounted; a substrate on which the light receiver is mounted; a fixing member including an accommodation space in which the substrates are accommodated; and a sealing resin contained in the accommodation space and sealing the substrate.
