Beschreibung
Zusammenfassung:	An optical module includes a translucent body, a vibrator that is tubular and supports the translucent body, a piezoelectric element located at the vibrator to vibrate the vibrator, and an inner-layer optical component at an inner side portion of the vibrator. The inner-layer optical component includes an inner-layer lens that faces the translucent body, a recess that is recessed in a thickness direction of the inner-layer lens and includes a curvature on a surface of the inner-layer lens facing the translucent body, and a gap is located between the translucent body and the recess of the inner-layer lens.
