PROBLEM TO BE SOLVED: To provide an agitation device and an automatic analyzer capable of improving agitation efficiency and measurement precision, and in which, lead is not used.SOLUTION: A piezoelectric transducer 51 is oscillated by application of voltage. A holding part 52 is coupled to the piezoelectric transducer 51. A spacer 53 is attached to the holding part 52. A blade 55 is attached to the spacer 53 and agitates a solution. The piezoelectric transducer 51 includes a piezoelectric material having an ABOtype perovskite structure, the piezoelectric material includes at least one kind of bismuth and potassium as an A site chemical element. |
