Zusammenfassung:	PROBLEM TO BE SOLVED: To suppress deterioration of fixing strength between a frame and a sealed container by preventing hardening of welded metal and generation of a gas due to transfer of carbon in the frame to a welded portion.SOLUTION: A displacement type compressor includes: a compressing mechanism portion; a motor portion for driving the compressing mechanism portion; a crank shaft for transmitting rotation of the motor portion to the compressing mechanism portion; and a sealed container 21 accommodating the compressing mechanism portion, the motor portion and the crank shaft. The compressing mechanism portion has a frame 12 having a bearing for supporting the crank shaft, and the frame is fixed to the sealed container through several welded portions. The welded portions between the frame and the sealed container are formed by inserting inclusions 24 of an iron-based material of a small content of carbon into through holes 22 formed on the sealed container in advance, and welding the same.
