Abstract:
An infrared ray detecting element includes: a substrate having a cavity; an infrared ray detecting portion including, sequentially stacked, a lower electrode layer, a detection layer, and an upper electrode layer; first and second support portions which support the infrared ray detecting portion above the cavity; and first and second external lead portions for leading electrical signals outputted from the infrared ray detecting portion, to the outside. The first support portion includes, sequentially stacked, a first upper wiring pattern, a first insulating layer, and a first lower wiring pattern. The upper electrode layer is connected to the first external lead portion via the first upper wiring pattern. The second support portion includes, sequentially stacked, a second upper wiring pattern, a second insulating layer, and a second lower wiring pattern. The lower electrode layer is connected to the second external lead portion via the second lower wiring pattern.
