<p>PROBLEM TO BE SOLVED: To provide a waterproof device that performs a determination of warrantable waterproof performance after a plurality of impacts is applied in a short time.SOLUTION: A waterproof device comprises: a first member that constitutes a housing; a second member that constitutes the housing, and is connected to the first member; a watertight member that is arranged between the first member and the second member, and is for maintaining a watertight state; an impact detection part 33 that detects a value about magnitude of the impact; a specification part 32 that specifies a direction where the impact is applied and an impact portion; a deformation detection part 33 that detects a degree of deformation of the watertight member in the impact portion on the basis of the specified direction and impact portion; and a waterproof determination part 32 that, after the value about the magnitude of the impact by a first impact is detected by the impact detection part, when a value about magnitude of an impact by a second impact is detected by the impact detection part until the housing is put into a stable state, determines a degree of warrantable waterproof performance on the basis of a first output of the deformation part by the first impact and a second output of the deformation detection part by the second impact.</p> |
