To provide an antenna sheet with an antenna pattern formed by etching, wherein poor communication by a chipped pattern due to overetching or side etching is reduced and proper communication characteristics are secured.

The antenna sheet has an antenna pattern containing a loop coil pattern composed of a conductive thin film on a base material sheet, wherein the loop coil pattern has the outermost periphery coil pattern, the innermost periphery coil pattern, and a middle coil pattern and a part or all of the outermost periphery coil pattern and the innermost periphery coil pattern are wider than a line width of the middle coil pattern.
