An abnormality diagnosis device to be used in a vehicle braking device equipped with a low pressure source connected to a reaction force chamber in a predetermined condition, a master cylinder, a drive portion, and a control portion. The abnormality diagnosis device includes: a diagnosis portion for performing an abnormality diagnosis on the basis of the relationship between the reaction force hydraulic pressure and the operation amount of a braking operation member, and/or the relationship between a target value and an actual value; and a judging portion for judging whether or not the reaction force chamber state pertaining to the hydraulic pressure and/or fluid amount thereof is in a predetermined insufficient state or in a predetermined excess state. Furthermore, when the judging portion judges that the reaction force chamber state is in a predetermined insufficient state or in a predetermined excess state, the diagnosis portion stops the abnormality diagnosis.
