PROBLEM TO BE SOLVED: To provide an ultrasonic measurement apparatus, capable of performing efficient scanning by a simple configuration, electronic equipment, a diagnostic apparatus, and an ultrasonic device.SOLUTION: An ultrasonic measurement apparatus 300 includes: an ultrasonic device 200 which has an ultrasonic element array 100; a first signal generation circuit 110 which supplies a first drive voltage to first-nth (n is an integer ≥2) first-direction terminals X1-Xn; and a second signal generation circuit 120 which supplies a second drive voltage to first-mth second-direction terminals Y1-Ym. The ultrasonic element array 100 comprises: a plurality of ultrasonic elements UE which are arranged in a matrix array pattern; first-nth first-direction electrode wires LX1-LXn which are arranged along a first direction D1 and which supply the first drive voltage to the plurality of ultrasonic elements; and first-mth second-direction electrode wires LY1-LYm which are arranged along a second direction D2 and which supply the second drive voltage to the plurality of ultrasonic elements. The second signal generation circuit 120 supplies the first-mth second-direction terminals Y1-Ym with the second drive voltages different from each other. |
