Abstract:
1. An infrared detector comprising: a circuit block carrying an infrared sensor element and electronic components; and a case enclosing said circuit block, said circuit block comprising a dielectric resin layer and a first substrate formed with a circuit pattern and mounting said electronic components, said dielectric resin layer being formed in its top with a recess which defines around its periphery a shoulder for supporting opposite ends of said infrared sensor element, said recess defining a heat insulation space below said infrared sensor element, said first substrate is integrated to the lower end of said dielectric resin layer with at least one of said electronic components being molded into said dielectric resin layer below said recess to make said circuit block of a unified mold structure, wherein said dielectric resin layer comprises a first resin layer formed with said recess, and a second resin layer embedding said at least one of the electronic components therein, a shield layer being disposed between said first and second resin layers for connection with a circuit ground of said circuit pattern.
