Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a bearing device for a wheel with a sensor in which an accurate load can be detected continuously in accordance with various input states by correcting the influence of a brake operation on a detected load in a bearing part.SOLUTION: A bearing 100 for a wheel comprises a sensor 20 which detects a load applied to the bearing, and further comprises signal processing means 31 which generates a signal vector from an output signal of the sensor, and load computation processing means 32 which computes the load applied to the wheel from the signal vector. In the load computation processing means 32, two kinds of load values corresponding to brake ON/OFF are computed by a load value computing section 33 and based on a result of comparing an evaluation value E which is outputted from an evaluation value output section 34 and becomes an index of a brake state determination, with a threshold value C, a load value corresponding to the brake state is selected and outputted from between the two kinds of load values by a load value output section 35. If the evaluation value E is settled within a determined range including the threshold value C, the two kinds of load values are combined in a predetermined ratio by an output load value correction section 36.
