A vibrating motor includes a stationary portion, and a movable portion able to vibrate with respect to the stationary portion along a center axis extending in a vertical direction. The stationary portion includes a bearing portion which supports the movable portion to be able to vibrate along the center axis and has a tubular shape extending along the center axis, a coil which directly opposes at least a portion of the movable portion in a radial direction, and a top surface portion which is above the movable portion and connected to the movable portion with an elastic portion therebetween. The bearing portion includes a first region which opposes the movable portion in the radial direction with a first gap therebetween, and a second region which is above the first region and opposes the movable portion in the radial direction with a second gap wider than the first gap therebetween.
