Abstract: A magnetic water activator resistant to corrosion such as rusting while soft on the outside, and exhibiting excellent portability also from the view point of a profile. The magnetic water activator comprises a pair of magnetic circuit constituting members formed of a high magnetic permeability material and forming a partial annular shape in which one end of each member is coupled to each other rotatably with each recess side facing each other, a permanent magnet arranged along the recess side of each magnetic circuit constituting member, and a substantially annular elastic resin shell partially provided with a slit extending in the radial direction, and internally burying and holding the magnetic circuit constituting member and the permanent magnet in an airtight state.
