Abstract

Provided is a marker for mobile communication that controls temperature increase of an electronic circuit board due to daytime insolation and temperature decrease due to nighttime radiation cooling and effectively balances heat dissipation of heat generated from electronic parts mounted on the circuit board. A wireless communications marker (1) established above ground characterized in having between the electronic circuit board (9) and the top surface of a housing (7) an insulation layer such as an air layer a vacuum layer a foam material layer or a fiber material layer and characterized in that the portion below the electronic circuit board (9) comprises only a material with higher heat conductivity than the insulation layer.
