<P>PROBLEM TO BE SOLVED: To provide an infrared detecting element having a structure in which an adhesion film is not easily formed in the space of the hollow structure even when the infrared detecting element is attached to a base plate with an adhesive. <P>SOLUTION: The infrared detecting element comprises: a first base plate 2 having a first front surface 2a, a first back surface 2b on the opposite side of the first front surface 2a, a first recessed portion 4 provided in the first back surface 2b, and an infrared detecting section 3 for detecting infrared rays provided in an area of the first front surface 2a that faces the first recessed portion 4; a second base plate 8 having a second front surface 8a, a second back surface 8b on the opposite side of the second front surface 8a, and a second recessed portion 9 provided in an area of the second back surface 8b that faces the first recessed portion 4; and an adhesion film 7 that bonds the first back surface 2b and the second back surface 8b. An adhesive is applied to the second front surface 8a. A second outer peripheral portion 9b where the second recessed portion 9 intersects with the second back surface 8b surrounds a first outer peripheral portion 4b where the first recessed portion 4 intersects with the first back surface 2b. <P>COPYRIGHT: (C)2013,JPO&INPIT |
