光検知器。 In a photodetector in which a base substrate is attached to a stem, a pyroelectric element is attached to the base substrate, a filter is placed on top of the pyroelectric element, and a cap is attached. Make one of the soldering lands in a shape different from the other lands to make it easier to check the directionality, and set the distance between each land on the base board from 0.20 mm to 0.40 mm.
A photodetector characterized in that the land on which the pyroelectric element is mounted and the elongated land adjoining the land are widened further, and a plurality of marks for positioning are provided between them.
