An antimicrobial laminate excelling in the ability to effect gradual release of an antimicrobial agent and providing an antimicrobial action evenly and bags and other containers using the antimicrobial laminate are disclosed. A substratal film 24 impervious to steam is provided on one side of a substratal film proper 22 of paper with a gas-barriering layer 23 of aluminum foil. An antimicrobial film 21a pervious to steam is formed by sequentially superposing an adhesive agent layer (AITC regenerating layer) 16a containing an AITC inclusion cyclodextrin compound 15 (fine powder), a steam-pervious film 17a having a fine powder of silica gel dispersed therein, an adhesive agent layer 16b identical in construction with the adhesive agent layer 16a, and a sealant material 17b of steam-pervious film in the order mentioned. An antimicrobial layer 121 is constructed by adhesively superposing the substratal film 24 and the antimicrobial film 21a through the medium of the adhesive agent layer 16a. A bag is constructed by folding the laminate with the sealant material 17b on the inner side and attaching a fastener of ridge-groove engagement to the mouth of the bag.
