Ultrasonic measurement device, ultrasonic head unit, ultrasonic probe, and ultrasonic image device

An ultrasonic measurement device comprising:

• an ultrasonic element array that has at least one reception ultrasonic element column equipped with ultrasonic elements for reception and that has at least one transmission ultrasonic element column equipped with ultrasonic elements for transmission;
• a reception terminal connected to the reception ultrasonic element column;
• a transmission terminal connected to the transmission ultrasonic element column;
• a reception circuit that receives a reception signal from the reception terminal;
• and
• a transmission circuit that outputs a transmission signal to the transmission terminal, wherein
• the at least one reception ultrasonic element column and the at least one transmission ultrasonic element column are alternately arranged every column, or any multiple of columns in a first direction, the first direction being a scanning direction,
• the ultrasonic elements in the reception ultrasonic element column are arranged along a second direction that is orthogonal to the first direction,
• the ultrasonic elements in the transmission ultrasonic element column are arranged along the second direction,
• the reception terminal is arranged at one end of the ultrasonic element array in the second direction, and the transmission terminal is arranged at the other end of the ultrasonic element array in the second direction.
