Provided are an ultrasonic probe that controls temperature of a piezoelectric layer using a thermoelectric element and an ultrasonic imaging apparatus having the same. The ultrasonic probe includes: the piezoelectric layer that vibrates and generates ultrasonic waves if a current is supplied to the piezoelectric layer； and a thermoelectric element that contacts one surface of the piezoelectric layer and controls the temperature of the piezoelectric layer if a current is supplied to the thermoelectric element.
