To provide a dynamic damper which can attenuate vibration while suppressing cost increase and mass increase.SOLUTION: This dynamic damper comprises: an orthogonal hexahedral weight (9a); a base part (8a) having a first wall part (8a1), a second wall part (8a2), and a third wall part (8a4) which respectively face a first face (9a1), a second face (9a2) connected to the first face (9a1), and a third face (9a4) connected to the first face (9a1) and the second face (9a2) among six faces of the weight (9a); a first connection part (9b) which elastically connects the first face (9a1) and the first wall part (8a1) to each other; a second connection part (9c) which elastically connects the second face (9a2) and the second wall part (8a2) to each other; and a third connection part (9d) which elastically connects the third face (9a4) and the third wall part (8a4) to each other.SELECTED DRAWING: Figure 2
