PROBLEM TO BE SOLVED: To provide an ultrasonic transducer device, an ultrasonic measurement apparatus and the like which can improve resolution of an ultrasonic image without reducing element size.SOLUTION: An ultrasonic transducer device 200 includes a first to n-th (n is an integer of 2 or more) ultrasonic transducer elements UE1 to UEn arranged in a zigzag way along a first direction D1. When a maximum length in the first direction D1 of the respective elements of the first to n-th ultrasonic transducer elements UE1 to UEn is defined as WX, a maximum length WY in a second direction D2 orthogonal to the first direction D1 is defined as WY, an arrangement pitch in the first direction D1 between a k-th (k is an integer that satisfies 1≤k≤n-1) element UEk and a (k+1)-th element UEk+1 is defined as PX, and an arrangement pitch in the second direction D2 is defined as PY, 0.5×WX≤PX<0.75×WX and PY
