The sensor bracket has a sensor holding portion holding the sensor electrode and is attached to an inner surface of the attached member. The sensor holding portion includes a holding piece that extends from a side away from an inner surface of the attached member to a side approaching the inner surface and holds the sensor electrode, and the holding piece holds the sensor electrode at a position at which an axis of the sensor electrode is separated from the inner surface of the attached member by at least 15 mm or more.

Disclosed is a device for detecting an intention of a user to lock or unlock an opening element of a motor vehicle. The device includes a capacitive sensor and incorporates an inductive sensor with an amagnetic metal target moving under the action of the hand of the user on the handle or the frame, the target being associated with a coil placed in an oscillating circuit being connected to an inductive measurement circuit detecting the intention of the user to lock or unlock the opening element. The intention is only confirmed when detected by both the capacitive and inductive sensors, the target of the inductive sensor being borne by the electrode of the capacitive sensor and a member supporting the electrode being elastically deformable under the action of the user on the handle or the frame, the inductive and capacitive measurement circuits being independent of each other.
