Abstract:
A double-sided adhesive tape has an adhesive member which is formed in the shape of a film and whose both surfaces in a thickness direction have an adhesive force and a pair of separation films which are arranged so as to sandwich the adhesive member in the thickness direction. The double-sided adhesive tape is formed so as to have a non-planar shape and to reduce the occurrence of wrinkles in the adhesive member when the adhesive member is adhered to a non-planar adherend.
