An antenna according to the present invention comprises: a plurality of parallel disposed linear conductors; two insulating films between which the plurality of linear conductors are sandwiched; at least one cut portion formed in at least one of the plurality of linear conductors; and a feed point connected to at least one of the plurality of linear conductors. With this configuration, the segment of the linear conductor connected to the feed point provides a driven element, while the other end of the linear conductor opposite to the feed point connected end is electrically open so that the segment of the linear conductor extending beyond the cut portion provides a parasitic element.
