Abstract
An optical sensor includes: a light emitting element; a lower substrateon which the light emitting elementis provided; an upper substrateprovided so that the light emitting elementis positioned between the upper substrateand the lower substrate; and an optical blockprovided on the upper substrate. The upper substrateincludes a division-type photodiode SD. The optical blockis configured to reflect light emitted from the light emitting elementtoward a measurement target R, and light reflected by the measurement target R is incident onto the division-type photodiode SD.
