Abstract
A reading device includes an antenna element, a substrate including a communication circuit and a ground plane, a connecting member protruding from the substrate in a thickness direction of the substrate and configured to electrically connect the communication circuit and the antenna element, and a casing configured to retain the antenna element, the substrate, and the connecting member. The antenna element is arranged separately from the substrate toward one side in the thickness direction. The casing includes a first surface portion that covers the substrate when viewed from the other side in the thickness direction. In a case where a distance in the thickness direction from a feed point to the ground plane is a first distance, and a distance in the thickness direction between the substrate and the first surface portion is a second distance, the first distance is greater than the second distance.
