Abstract
A cooled CCD camera includes a CCD, a heat transfer plate, a cooling element for cooling the CCD, at least one substrate on which electronic parts are mounted and an airtight package for accommodating them, the package being made of aluminum alloy, an optical glass plate being airtightly mounted on the package by sealing with glass having a melting point from 400 to 450.degree. C. and connector terminals for connecting the CCD to the outside being airtightly mounted on the package by sealing with glass having a melting point from 400 to 450.degree. C. The thus constituted cooled CCD camera has simple structure, is easy to mount and has improved cooling efficiency.
