The present invention is directed to surface functionalized fabrics, particularly those based on non-woven polypropylene, wherein the functional groups are capable of binding antimicrobial agents through ionic conjugation to control their release and prolong their antimicrobial activity. The second surface of the first wiring substrate and the first surface of the second wiring substrate are mated in the state where the second wire bonding terminal sections are exposed. The lid has a downwardly extending flange.
