Abstract: A phototransistor includes a first emitter region, a first base region having at least a portion exposed to a light-receiving side, and a first collector region in this order from the light-receiving side in a depth direction. The first collector region includes a second collector region and a third collector region that is in contact with a downstream side of the second collector region in the depth direction and has a resistance lower than that of the second collector region. The phototransistor further includes a first region that is spaced away from the first base region at an outer side of the first base region on a light-receiving side surface thereof, the first region having a conductivity type opposite to that of the first collector region.

Abstract: An inspection device is provided including a light emitting element configured to emit light, a light receiving element arranged so as to face the light emitting element and configured to receive the light, where one of the light emitting element and the light receiving element is used as a to-be-inspected element, and the other one of the light emitting element and the light receiving element is used as an inspection element that inspects the to-be-inspected element, a housing configured to accommodate the inspection element, and a lid configured to be detachable from the housing. In the inspection device, one of the housing and the lid is provided with an arrangement unit to which the to-be-inspected element is set in a detachable manner, and the lid includes a contact unit that electrically contacts the to-be-inspected element by touching and detaching from the to-be-inspected element.
