PROBLEM TO BE SOLVED: To provide a mobile body communicating marker that can hold axial force of a fastening body to prevent slack even after elapse of a long time since fastening.SOLUTION: The mobile body communicating marker includes: a housing provided with an electronic substrate therein; a pedestal for supporting the housing; and the fastening body for fastening the housing with the pedestal. The housing is molded of a resin expanding and contracting in response to temperature fluctuation and the fastening body has a substantially same linear expansion coefficient as a linear expansion coefficient of the housing.SELECTED DRAWING: Figure 3 【課題】締結してから長時間経過した後であっても、締結体の軸力を保持して緩みを防止し得る移動体通信用マーカーを提案する。【解決手段】電子基板を内部に備える筐体と、筐体を支持する台座と、筐体と台座とを締結する締結体とを備え、筐体は、温度変動に応じて膨張又は収縮する樹脂により成型され、締結体は、筐体の線膨張係数と略同一の線膨張係数を有することを特徴とする。【選択図】図３
