摘要： There is provided an antenna whose outside shape can be miniaturized while maintaining a gain at a desired level with respect to a radio wave of a wide frequency range. The antenna is configured by using a core of a laminate structure. The core is a plate of a rectangular outside shape, configured to have a laminate structure including each of first, second and third resin layers. The first resin layer has magnetic powder mixed therein and formed as a middle layer, and the second resin layer and the third resin layer made of resin only without magnetic powder mixed therein are formed to sandwich the first resin layer therebetween. In the core of the laminate structure, it is preferable to use a polymer resin for each of the resin layers, and to use soft ferrite powder as the magnetic powder.
