Photosensor having an emitter-encapsulating portion, receiver-encapsulating portion, and circuit-encapsulating portion connected to one another with a conductive leadframe

A photosensor, comprising:

• an emitter element;
• an emitter-encapsulating portion encapsulating the emitter element;
• a receiver element;
• a receiver-encapsulating portion encapsulating the receiver element;
• a circuit portion including a luminous element for indicating an operation;
• and
• a circuit-encapsulating portion encapsulating the circuit portion and including an operation indicator portion facing the luminous element,
• wherein the thickness of a resin portion of the receiver-encapsulating portion covering a light receiving surface of the receiver element in a direction perpendicular to the light receiving surface is smaller than the thickness of a resin portion of the circuit-encapsulating portion covering a luminous surface of the luminous element in a direction perpendicular to the luminous surface.
