Abstract: A light-transmissive antenna includes: a transparent base made of a transparent insulating material; and an antenna pattern formed on the transparent base. The antenna pattern is made of a transparent electrically conductive film that is a film-like member having a predetermined transmittance and a predetermined electrical conductivity. The light-transmissive antenna includes a plurality of highly electrically conductive patterns arranged on the antenna pattern, each of the highly electrically conductive patterns being made of an electrically conducive member having a higher electrical conductivity than the transparent electrically conductive film and formed in a linear shape. Each of the plurality of highly electrically conductive patterns has a predetermined width set equal to or smaller than a value assumed as a resolution of human eyes.
