Abstract
A method of manufacturing a photodetection device includes preparing a first substrate having a first electrode; forming, on the first substrate, a photoresist film having an opening through which the first electrode is exposed; forming, through the opening, a metallic film containing a first metal on the first electrode; and removing, after the forming of the metallic film, the photoresist film. The forming of the metallic film includes vapor-depositing the metallic film on the first electrode and on the photoresist film, and heating the metallic film formed on the photoresist film.
