Abstract
An electromagnetic wave shielding film includes: a protective layer; a shield layer laminated on the protective layer; and an adhesive layer laminated on the shield layer. Conductive bumps are formed on a side of the adhesive layer of the shield layer. The conductive bumps are positioned on a tessellation of one kind of polygon at vertices of respective polygons, and the conductive bumps are arranged such that, with respect to each of the conductive bumps, when drawing line segments connecting respective conductive bumps and nearest conductive bumps at a nearest position and drawing a straight line passing through one line segment among the drawn line segments, the straight line has a portion that does not overlap with the other line segments.
