A vibration actuator, comprising: a fixing body including a coil (61, 62); a movable body including a magnet that is disposed inside the coil (61, 62) in a radial direction of the coil (61, 62) to be relatively movable in a vibration direction orthogonal to the radial direction of the coil (61, 62); and an elastic supporting part (81, 82) that supports the movable body such that the movable body is freely movable with respect to the fixing body, wherein cooperation between the coil (61, 62) supplied with electricity and the magnet causes the movable body to vibrate with respect to the fixing body, the fixing body includes a bobbin-shaped coil holding part that is disposed to surround the magnet externally in the radial direction and holds the coil (61, 62) disposed outside the bobbin-shaped coil holding part in the radial direction, the bobbin-shaped coil holding part includes a coil protection wall portion that is disposed inside the coil (61, 62) in the radial direction of the coil (61, 62) with a gap being interposed between the bobbin-shaped coil holding part and the magnet, the coil protection wall portion inhibiting contact between the coil (61, 62) and the movable body including the magnet, the elastic supporting part (81, 82) includes at least two or more leaf springs installed between the movable body and the fixing body to sandwich the movable body in the vibration direction, the at least two or more leaf springs support the movable body such that, in a non-vibration state and in a vibration state of the movable body, the movable body is freely movable in the vibration direction without making contact with the bobbin-shaped coil holding part, a coil connection part to which the coil (61, 62) is connected is disposed on the bobbin-shaped coil holding part to protrude, wherein the bobbin-shaped coil holding part includes a flange-shaped central wall portion projecting in the radial direction at a central portion in the vibration direction, and holds a first coil and a second coil constituting the coil such that the first coil and the second coil are arranged side by side to sandwich the flange-shaped central wall portion in the vibration direction, and the flange-shaped central wall portion includes: the coil connection part, and a groove portion disposed in an outer circumferential portion of the flange-shaped central wall portion to open outward in the radial direction, and in which a coil wire linking the first coil to the second coil is disposed. a fixing body including a coil (61, 62); a movable body including a magnet that is disposed inside the coil (61, 62) in a radial direction of the coil (61, 62) to be relatively movable in a vibration direction orthogonal to the radial direction of the coil (61, 62); and an elastic supporting part (81, 82) that supports the movable body such that the movable body is freely movable with respect to the fixing body, wherein cooperation between the coil (61, 62) supplied with electricity and the magnet causes the movable body to vibrate with respect to the fixing body, the fixing body includes a bobbin-shaped coil holding part that is disposed to surround the magnet externally in the radial direction and holds the coil (61, 62) disposed outside the bobbin-shaped coil holding part in the radial direction, the bobbin-shaped coil holding part includes a coil protection wall portion that is disposed inside the coil (61, 62) in the radial direction of the coil (61, 62) with a gap being interposed between the bobbin-shaped coil holding part and the magnet, the coil protection wall portion inhibiting contact between the coil (61, 62) and the movable body including the magnet, the elastic supporting part (81, 82) includes at least two or more leaf springs installed between the movable body and the fixing body to sandwich the movable body in the vibration direction, the at least two or more leaf springs support the movable body such that, in a non-vibration state and in a vibration state of the movable body, the movable body is freely movable in the vibration direction without making contact with the bobbin-shaped coil holding part, a coil connection part to which the coil (61, 62) is connected is disposed on the bobbin-shaped coil holding part to protrude, wherein the bobbin-shaped coil holding part includes a flange-shaped central wall portion projecting in the radial direction at a central portion in the vibration direction, and holds a first coil and a second coil constituting the coil such that the first coil and the second coil are arranged side by side to sandwich the flange-shaped central wall portion in the vibration direction, and the flange-shaped central wall portion includes: the coil connection part, and a groove portion disposed in an outer circumferential portion of the flange-shaped central wall portion to open outward in the radial direction, and in which a coil wire linking the first coil to the second coil is disposed. the coil connection part, and a groove portion disposed in an outer circumferential portion of the flange-shaped central wall portion to open outward in the radial direction, and in which a coil wire linking the first coil to the second coil is disposed.
