The present invention relates to an apparatus for detecting the overflow of residual water in a mixer drum of a ready-mixed concrete car, comprising: level sensors (10, 10') of a group installed to have a current applied when the allowable residual water volume is exceeded on the cleaning residual water part in the mixer drum (2) of the ready mixed concrete car; a level electrode (20) connected to a sensor window (11) of the level sensors (10, 10') and coupled to an extension unit (12) exposed on an outer surface of the mixer drum (2); a contact driving unit (30) having a contact plate (31) apart from the level electrode (20) in ordinary times but electrically coming in contact with the level electrode (20) when an electromagnet is driven; and a measurement control apparatus (50) detecting a contact direction of the contact plate (31) and the recognized value of the level sensors (10, 10') in case of contact, and driving a warning lamp (40) when the residual water volume overflows. The contact driving unit (30) includes: a moving pipe (33) supporting the contact plate (31) and accommodating an electric wire (32) connected to the measurement control apparatus (50) inside; a permanent magnet (34) coupled to a rising/falling rear end of the moving pipe (33); an electromagnet (36) apart from the permanent magnet (34) by the snapping force of the spring (35) and being coaxial with the moving pipe (33) and movably installed; and a housing (37) fixing the electromagnet (36) and supporting to elevate the permanent magnet (34) when the electromagnet (36) is magnetized, and fixed on a ready mixed concrete car chassis (6) by a screw (38).
