Abstract
To provide a mounting structure for a gas adsorption filter and a housing equipped with the gas adsorption filter that make it possible to overcome the contradiction between achieving a further reduction in the size of airtight containers such as casings for magnetic storage disk devices, and ensuring improved control over moisture, noxious gases, and other types of contaminants in the airtight containers. A mounting structure for a gas adsorption filter to be mounted in an airtight container, wherein the gas adsorption filter 11a is obtained by providing an adsorbent 13 to one or both sides of a base 12, covering the adsorbent 13 with a breathable member 14 to form an adsorbent unit, bonding together the breathable member 14 and the peripheral portion of the adsorbent 13 on the base 12 to form a collar 15, fitting the adsorbent unit of the gas adsorption filter 11a into a mounting hole formed in the airtight container, and bonding the collar 15 of the gas adsorption filter 11a to the peripheral portion of the mounting hole outside the airtight container.
