Abstract
To provide an IC-tagged bearing device, in which difficulties brought about by reflection and/or absorption of radio waves upon and/or in raceway members or the like can be avoided, information recording can be accomplished satisfactorily, an IC tag itself does not require an antenna, and the IC tag can have a compact, yet large capacity. The bearing device, having a bearing space delimited between inner and outer races () and sealed by a sealing member (), includes an IC tag () which utilizes a core metal () as an antenna and which is fitted to the sealing member (). The sealing member () is made of a rubber material or a synthetic resin having the core metal ().
