Abstract
Provided is an electromagnetic wave propagation sheet constituted by a mesh-shaped conductor layer, a planar conductor layer, and an inductor layer sandwiched therebetween, wherein the mesh-shaped conductor layer and the planar conductor layer are electrically connected to each other in an end section of the electromagnetic wave propagation sheet by a short conductor, and a mesh-shaped conductor that constitutes the mesh-shaped conductor layer has a meander shape in the vicinity of the electromagnetic wave propagation sheet end section.
