PROBLEM TO BE SOLVED: To provide a cooling device for very low temperature capable of reducing the manufacturing cost and performing the efficient cooling. SOLUTION: This cooling device comprises a compressor 2a having the cylindrical outer shape, and an integrated radiator 3a for the compressor, having a cylindrical inner face same as the compressor. The integrated radiator 3a for the compressor has groups of fins composed of parallel fins of high concentration on a plurality of parts of its outer face, and has a clearance part for separating a part of the circumference, and a fastening part 34 for fixing, on its lower part. As a clearance of the clearance part can be adjusted on the basis of a screwing state of a screw 36 to the fastening part 34 for fixing, the radiator can be easily fitted to the compressor 2a, and can be easily and surely adhered and fixed to the compressor 2a.
