Abstract
An infrared detector comprises: first and second container members bonded to each other along an annular bonding portion to define a vacuum-sealed inner space, where the second container member has an infrared-transmissive property; an infrared detecting element disposed in the inner space; a first annular metallization layer formed on the bonding portion of the first container member; a second annular metallization layer formed on the bonding portion of the second container member; a solder metal for air-tightly bonding the first metallization layer and the second metallization layer; and a third metallization layer formed in a vicinity of one of the first and second metallization layers such that the third metallization layer overlaps the other of the first and second metallization layers at least partly.
