Two sheets of film element (4) are used to sandwich an adsorbing body (2) vertically to bond the two film elements (4) to the upper and lower surfaces of the adsorbing body (2). Skirt sections (4A) extending sidewise from the adsorbing body (2) are formed at the outer edge sides of respective film elements (4) to form vaporizing openings (8) between respective skirt sections (4A). A freshness preserving liquid impregnated in the adsorbing body (2) is gradually vaporized from the respective side surfaces (2A) of the adsorbing body (2) to the outside via the vaporizing openings (8), whereby it is possible to prevent the adsorbing body (2) of the freshness preserving gadget (1) from directly touching foods and preserve the freshness of foods constantly over an extended period.
