A sensor-equipped bearing device for wheel, capable of maintaining sealability by preventing an occurrence of cracks and a dimensional variation caused by water absorption into a sensor installation member. Of an outer member (1) and an inner member (2), the member on the stationary side is provided with the sensor installation member (12) that forms a sealed space (11) communicating with the space between the inner and outer members (1, 2). A sensor element (10c) for detecting the state of the bearing device (A) is attached to the sensor installation member (12). The sensor installation member (12) is made of a plastic material having a low water absorption coefficient. Cette invention concerne un dispositif de palier pour roue muni d'un capteur, permettant de maintenir l'étanchéité par prévention d'une apparition de fissures et d'une variation dimensionnelle en raison de l'absorption d'eau dans un élément de montage de capteur. Un élément externe (1) ou un élément interne (2) disposé sur un côté fixe comprend un élément de montage de capteur (12) qui forme un espace scellé (11) communiquant avec l'espace entre les éléments interne et externe (1, 2). Un capteur (10c) destiné à détecter l'état du dispositif de palier (A) est fixé à l'élément de montage de capteur (12). L'élément de montage de capteur (12) est composé d'une matière plastique dotée d'un faible coefficient d'absorption d'eau.
