    摘要： A two-dimensional array ultrasonic probe includes a plurality of channels arranged apart from each other in a two-dimensional direction, each channel including a laminated piezoelectric element and an acoustic matching layer formed on the laminated piezoelectric element, the laminated piezoelectric element including a plurality of first and second electrodes arranged alternately within a piezoelectric body in a thickness direction of the piezoelectric body such that the side edges alone of the first electrodes and the second electrodes are exposed to the two mutually facing side surfaces of the piezoelectric body, respectively. The laminated piezoelectric element is mounted to a backing member. A signal side electrode and a ground electrode are formed to respectively extend from both side surface of the piezoelectric body to reach the backing member and are connected to the side edges of the first and second electrodes exposed to the side surface of piezoelectric body, respectively.

    摘要： There is provided a printing device configured to eject a dispersed body containing a solid particle and a liquid. The printing device includes a film and an acoustic head. The film has a first major surface and a second major surface on an opposite side of the first major surface. The first major surface is provided with a first recess accommodating the liquid and a second recess provided on a bottom face of the first recess and accommodating the solid particle. The acoustic head focuses an acoustic wave from a side of the second major surface toward the first recess and the second recess. Thus, even in the case of discharging a dispersed body containing solid particles, it is possible to uniformize the amount of solid particles contained in ejected droplets and it is possible to uniformly make a print.
