Abstract

The invention relates to a device for monitoring the physical parameter of a tyre condition, that comprises a sub-assembly (1) arranged inside said tyre and comprising a resonant electric circuit (11) including a magnetic induction coil (110). According to the invention, the resonant circuit (11) has a flat shape with a thickness (El), parallel to the axis (Z) of the coil (110), not exceeding one fifth of each of the other two dimensions, and said circuit is directly imbedded in a protection coating (12) having a flat shape with a thickness (E2) parallel to that of the resonant circuit (11), the sub-assembly (1) formed by said circuit (11) imbedded in said coating (12) being arranged so as to be capable of free movement in the tyre.
