Zusammenfassung:	A buzzer unit 4 includes a case 10, a vibrating element 11, and a pressing member 14. The case 10 includes a vibrating plate 28 in which no through-holes are formed. The case 10 includes a storage space 22 formed therein on the lower side X2 of the vibrating plate 28. The vibrating element 11 faces the vibrating plate 28 in the vertical direction X inside the storage space 22, produces vibration as a result of voltage being applied thereto, and as a result, causes the vibrating plate 28 to vibrate. The pressing member 14 is stored in the storage space 22, and presses the vibrating element 11 against the vibrating plate 28.
