An optical detection unit includes a first wiring substrate that has a first main surface, a plurality of optical detection chips that each have a light receiving surface and a rear surface on a side opposite to the light receiving surface and are two-dimensionally arranged on the first main surface, a first bump electrode that electrically connects the optical detection chip to the first wiring substrate, a light transmitting portion that is provided on the light receiving surface, and a light shielding portion that has light reflection properties or light absorption properties. The optical detection chip includes a Geiger-mode APD and is mounted on the first wiring substrate by the first bump electrode in a state in which the rear surface faces the first main surface.

Optical detection unit, optical detection device, and method for manufacturing optical detection unit

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.

An ultraviolet sensor includes a silicon photodiode array having a plurality of first pixel regions and a plurality of second pixel regions. A filter film is disposed on each of the first pixel regions so as to cover each first pixel region, except on each second pixel region. The filter film lowers transmittance in a detection target wavelength range in the ultraviolet region. Each of each first pixel region and each second pixel region includes at least one pixel having an avalanche photodiode to operate in Geiger mode, and a quenching resistor connected in series to the avalanche photodiode. Each of the quenching resistors in the plurality of first pixel regions is connected through a first signal line to a first output terminal. Each of the quenching resistors in the plurality of second pixel regions is connected through a second signal line to a second output terminal.
