To provide an electric washing machine sterilizing various germs as much as possible, which adheres to/remains in an object to be washed, without using a harmful germicide, a dangerous and expensive sterilization device, or the like.

Light source bodies 1, which are sufficient to demonstrate a sterilizing action by a photocatalyst, are installed on the inside of an inside part corresponding or/and a dehydration receptacle of an object-holding tank in the electric washing machine 2. Moreover, a sterilizing implement, which is used as a set with the light source bodies, is an approximately spherical body 3 which has a bulk specific gravity of 1.5 or less and is formed of a photocatalyst type material at least on the surface.
