The antenna-equipped film includes: a film base; an antenna pattern formed on the film base; and a number-of-winding setting circuit connected to the antenna pattern. The antenna pattern is formed as a plurality of linear loops. The number-of-winding setting circuit includes: first wiring connected to the antenna pattern to constitute a spiral circuit; jumper switches intervening by two each in each lap of the spiral circuit; second wiring connected to the end portion of the innermost lap of the spiral circuit and a position between the two jumper switches in each lap excluding the innermost lap and the outermost lap of the spiral circuit; third wiring connected in common to the other ends of the second wiring; and jumper switches intervening in the second wiring. The outer end of the spiral circuit and the third wiring constitute a pair of terminals.
