PROBLEM TO BE SOLVED: To provide a vibration unit that can improve vibration transmission efficiency of a vibrator and a seat with a vibration unit.SOLUTION: A seat 1A with a vibration unit comprises a seat 2, a vibration unit 5A and control means, and constitutes a driver seat of/in a vehicle. The vibration unit 5A is arranged in a storage recessed part 34 provided in a cushioning member of a seat part 3. The vibration unit 5A comprises a pair of vibrators 7L and 7R that generate vibrations, a pair of plate-like members 8 and 8 fixed to the vibrators 7L and 7R respectively, and surrounding members 9 covering the pair of vibrators 7L and 7R and the pair of plate-like members 8 and 8. In the vibration unit 5A, urethane form of the surrounding members 9 is densely filled into the circumferences of the vibrators 7L and 7R, and the surrounding members 9 are densely arranged between vibration surfaces of the vibrators 7L and 7R and the cushioning member of the seat part 3.SELECTED DRAWING: Figure 2
