Adhesive tape, method for manufacturing hard disk drive, and hard disk drive sealing structure

Abstract

An object of the present invention is to provide an adhesive tape excellent in barrier ability and L-shaped bending applicability. Another object of the present invention is to provide a method for manufacturing a hard disk drive excellent in sealability even in the case of sealing of a housing from the exterior of the housing, by use of the adhesive tape. Still another object of the present invention is to provide a hard disk drive sealing structure body sufficiently sealed even in the case of sealing of a housing from the exterior of the housing. The present invention relates to an adhesive tape having a water vapor transmission rate at 40° C. and 90% RH of 7.5 g/(m2·day) or 10 less, a bending rigidity at 25° C. at a bending width of 2.0 mm in at least one direction of a MD or a TD, of 1.0 N·mm2 or less, and a 180° peel force against SUS at 23° C. of 5.0 N/25 mm or more.
