A magnet (22) is provided to a vibrating plate (23) within a detection pipe unit (1) and an electromagnet (21) is placed opposite to the magnet with a slight gap therebetween. A drive circuit (51) applies, to a coil at every predetermined measurement cycle, an alternating current at a frequency which is swept over a predetermined range centered at a resonance frequency of the vibrating plate (23). When the alternating current is applied, a phase comparison circuit (53) detects a change in phase that is caused according to whether or not an object contacts the vibrating plate (23). A microcomputer (40) determines presence/absence of the object based on the detected change in phase, measures the temperature based on the detected change in phase in a former half cycle of the predetermined measurement cycle and changes the swept frequency based on the result of measurement of the temperature in a latter half cycle of the predetermined cycle.
