<p>A degassing apparatus (1) is provided that accomplishes the connecting of a degassing element (4) and a connecting member (5) and/or the joining of a vacuum (reduced-pressure) chamber (3) and the connecting member without using a fastening structure effected by a fastening means screwed together with the connecting member. A degassing apparatus includes: a reduced-pressure chamber having a through port (2) for flowing a degassing target liquid therethrough; a degassing element, accommodated in the chamber, for passing the liquid therethrough; and a tubular connecting member joined to the chamber at the through port. The degassing element includes a gas-permeable tube (7), for passing the liquid therethrough, being covered with a joint piece (8) at an end portion of the gas-permeable tube. The degassing element is fixed to the chamber by heat sealing the connecting member and the joint piece together.</p> |
