摘要（英）：

The invention provides an ultrasonic measurement device and an ultrasonic imaging device. The ultrasonic measurement device 100 includes a pulse signal output circuit 110 that outputs a pulse signal having a rectangular wave based on a clock signal, and a resonance circuit 120 that is connected to an output node of the pulse signal output circuit 110, includes an ultrasonic transducer element, and has frequency characteristics of a low-pass filter. Also, the pulse signal output circuit 110 outputs a plurality of pulse signals that are different from each other in at least one of pulse signal voltage, pulse signal width, and pulse output timing.
