Abstract
Abstract A pyro-electric type infrared-ray sensor comprises a pyro-electric thin film such as Pb TiO3, an upper electrode of Al film formed on the upper surface of the pyro-electric thin film, a lower electrode thin film of Al formed on the bottom surface thereof and an organic thin film which covers the upper surface, and the sensor further comprises an infrared light reflection member, at least partially on the surface of the organic thin film.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
73 words
A pyro-electric type infrared-ray sensor comprising: a pyro-electric thin film; a first electrode thin film formed on a first surface of said pyro-electric thin film; a second electrode thin film formed on a second surface of said pyro-electric thin film; an organic thin film which covers the first surface of said pyro-electric thin film; and an optical element for reflecting infrared-rays provided at least partially on the surface of the organic thin film.
Claim 2
Dependent Claim
73 words
A pyro-electric type infrared-ray sensor comprising: a pyro-electric thin film; a first electrode thin film formed on a first surface of said pyro-electric thin film; a second electrode thin film formed on a second surface of said pyro-electric thin film; an organic thin film which covers the first surface of said pyro-electric thin film; and an optical element for reflecting infrared-rays provided at least partially on the surface of the organic thin film.
Claim 3
Dependent Claim
83 words
A pyro-electric type infrared-ray sensor comprising: a pyro-electric thin film; a first electrode thin film formed on a first surface of said pyro-electric thin film; a second electrode thin film formed on a second surface of said pyro-electric thin film; an organic thin film which covers the first surface of said pyro-electric thin film; and an optical element for reflecting infrared-rays provided at least partially in the organic thin film and disposed in substantial parallelism to the surface of the pyro-electric thin film.
Claim 4
Dependent Claim
83 words
A pyro-electric type infrared-ray sensor comprising: a pyro-electric thin film; a first electrode thin film formed on a first surface of said pyro-electric thin film; a second electrode thin film formed on a second surface of said pyro-electric thin film; an organic thin film which covers the first surface of said pyro-electric thin film; and an optical element for reflecting infrared-rays provided at least partially in the organic thin film and disposed in substantial parallelism to the surface of the pyro-electric thin film.
