A shock absorbent device capable of securely protecting physical parts such as the lumbar part and femur part from a shock even imparted intensively to a narrow area of the physical part to be protected. Also, the shock absorbent device or a protective pad and protective clothes using the shock absorbent can be brought into close contact with the physical part to be protected while improving air permeability around the physical part covered with the protective pad or clothes and vary the area contacting with the physical part to be protected. The shock absorbent can be used for a protective pad for protecting physical parts such as the lumbar part and femur part from an external shock exerted thereto and includes a shock dispersing member (2), embedded in a shock absorbing member (1), for absorbing the external shock.
