PROBLEM TO BE SOLVED: To facilitate replacement work accompanied by specification change or the like of a detection sensor.SOLUTION: A bearing 1 with a wireless sensor includes a bearing body 5, a detection sensor provided on the bearing body 5 and detecting a physical quantity related to the bearing body 5, a radio communication processing unit provided on the bearing body 5 and transmitting detection information by the detection sensor by radio communication, and a power generating unit provided on the bearing body 5 and supplying electric power to the detection sensor and the radio communication processing unit. The detection sensor and the radio communication processing unit are respectively mounted on a sensor substrate 31 and a radio communication substrate 32. In replacing the detection sensor due to the specification change, only the sensor substrate 31 on which the detection sensor is mounted is required to be replaced, and redesigning of the radio communication processing unit is not required even in the case of redesigning the substrate itself due to the specification change of the detection sensor, and design work can be simplified accordingly, and the replacement work can be facilitated.SELECTED DRAWING: Figure 1 |
