To provide a texture presentation device that can sufficiently prevent water or food from attaching to an ultrasonic transducer and a reflector if the ultrasonic transducer or the reflector is touched by fingers or hands with water or food thereon, and also can make water or food removed forcibly if water or food gets attached to the ultrasonic transducer.SOLUTION: An ultrasonic wave texture presentation device 10 includes: an ultrasonic transducers 1; a supporting substrate 2 on which the ultrasonic transducers are set; a reflector 3 set in a position facing the ultrasonic transducers, the reflector reflecting ultrasonic waves oscillated from the ultrasonic transducers; and a housing 4 surrounding the ultrasonic transducers, the supporting substrate, and the reflector and having at least one opening, the ultrasonic wave 1y reflected from the reflector 3 collecting at the collection position A outside the housing set outside the housing 4 through the opening 40.SELECTED DRAWING: Figure 1 【課題】水および／または食材等の異物が付着した手および／または指で操作を行っても、当該異物の超音波振動子および反射面への付着を十分に防止することができ、仮に付着しても、付着物を強制的に排出することができる触感提示装置を提供すること。【解決手段】複数の超音波振動子１と、前記複数の超音波振動子を設置する支持基板２と、前記超音波振動子に対向する位置に設置され、かつ前記超音波振動子から発振された超音波を反射させる反射面３と、前記超音波振動子、前記支持基板および前記反射面を取り囲み、かつ少なくとも１つの開口部を有する筐体４と、を備え、前記反射面３で反射された前記超音波１ｙが前記開口部４０を通して前記筐体４の外に設定された筐体外集束位置Ａに集束することを特徴とする超音波触感提示装置１０。【選択図】図１
