First claim
Opening claim text (preview).
What is claimed is: 1 . An ultrasonic device comprising: a vibration film provided with a vibration region that is vibratable by a vibration element; and a damper layer that is provided to cover the vibration region of the vibration film, wherein the damper layer has a thickness dimension of 13 μm or larger and 25 μm or smaller. 2 . The ultrasonic device according to claim 1 , wherein the damper layer is formed of a material having Young's modulus of 150 or lower. 3 . The ultrasonic device according to claim 1 , wherein the vibration element is a piezoelectric element that includes a lower electrode provided on a surface of the vibration film, a piezoelectric layer laminated on the lower electrode, and an upper electrode laminated on the piezoelectric layer, and wherein the damper layer is provided on the surface of the vibration film on which the piezoelectric element is provided. 4 . The ultrasonic device according to claim 1 , wherein a direction in which an ultrasonic wave is transmitted when the vibration element causes the vibration region to vibrate is set as a first direction, and wherein the damper layer is provided on a surface of the vibration film on an opposite side to the first direction. 5 . An ultrasonic measuring apparatus comprising: the ultrasonic device according to claim 1 ; and a controller that controls the ultrasonic device. 6 . An ultrasonic measuring apparatus comprising: the ultrasonic device according to claim 2 ; and a controller that controls the ultrasonic device. 7 . An ultrasonic measuring apparatus comprising: the ultrasonic device according to claim 3 ; and a controller that controls the ultrasonic device. 8 . An ultrasonic measuring apparatus comprising: the ultrasonic device according to claim 4 ; and a controller that controls the ultrasonic device.
