PROBLEM TO BE SOLVED: To provide a wireless communication device with which it is possible to further improve the accuracy of detecting the temperature of an object.SOLUTION: A wireless communication device with a temperature sensor according to the present invention comprises: a coil antenna； a wireless communication circuit for communicating by wireless with an external apparatus via the coil antenna； a temperature sensor for detecting the temperature of an object； a control circuit for controlling the drive of the temperature sensor； and a flexible base sheet on one main surface of which are mounted the coil antenna, the wireless communication circuit, the control circuit, and the temperature sensor. An adhesive layer is provided on one main surface of the flexible base sheet. The flexible base sheet is attached to an object via the adhesive layer, the thickness of the flexible base sheet being thinner than the thickness of the adhesive layer, and the temperature sensor is provided so as to protrude toward a side in the thickness direction of the flexible base sheet more apart from the flexible base sheet than the surface of the adhesive layer.SELECTED DRAWING: Figure 4【課題】対象物の温度の検知精度を一層向上させることができる無線通信デバイスを提供する。【解決手段】本発明に係る温度センサ付き無線通信デバイスは、コイルアンテナと、コイルアンテナを介して外部機器と無線通信を行う無線通信回路と、対象物の温度を検知する温度センサと、温度センサの駆動を制御する制御回路と、コイルアンテナ、無線通信回路、制御回路、及び温度センサが一方の主面に実装される可撓性基材シートとを備え、可撓性基材シートの一方の主面には接着層が設けられ、可撓性基材シートは、接着層を介して対象物に取り付けられるものであり、可撓性基材シートの厚さが接着層の厚さよりも薄く、可撓性基材シートの厚さ方向において、温度センサが接着層の表面よりも可撓性基材シートから離れる側に突出するように設けられている。【選択図】図４
