Provided is an oriented piezoelectric ceramic of satisfactory piezoelectricity, which includes a metal oxide represented by (1âˆ’x)NaNbO 3 -xBaTiO 3 . Also provided are a piezoelectric element using the oriented piezoelectric ceramic which includes the metal oxide represented by (1âˆ’x)NaNbO 3 -xBaTiO 3 , and a liquid discharge head, an ultrasonic motor, and a dust removing device which use the piezoelectric element. An oriented piezoelectric ceramic includes as a main component a metal oxide represented by the following general formula (1), in which the oriented piezoelectric ceramic has a lead content and a potassium content that are each 1,000 ppm or less: (1âˆ’x)NaNbO 3 -xBaTiO 3 . . . General formula (1), where a relationship of 0<x<0.3 is satisfied.
