Infrared detecting element and electronic device

An infrared detecting element comprising:

• a first base plate that has a first surface, a second surface on the opposite side of the first surface, a first recessed portion provided in the second surface, and an infrared detecting section for detecting infrared rays provided in an area of the first surface that opposes the first recessed portion;
• a second base plate that has a third surface, a fourth surface on the opposite side of the third surface, and a second recessed portion provided in an area of the fourth surface that faces the first recessed portion;
• and
• an adhesion film that bonds the second surface and the fourth surface,
• wherein a second outer peripheral portion where the second recessed portion intersects with the fourth surface surrounds a first outer peripheral portion where the first recessed portion intersects with the second surface, and
• the second base plate has a side surface, and the second base plate has a channel portion formed in the second base plate between the second recessed portion and the side surface.
