This invention relates to a novel design of detachable/attachable magnetic buttons that can be used on clothes, accessories, and the like. Specifically, the invention also relates to a contact guiding structure of the button for a smooth detaching/attaching and an improved stability thereof.The magnetic button of the present invention is arranged so that the magnets on the flap and the body have opposite polarities from each other. Each magnet housing is placed around each magnet in order to make one magnet to be placed in that of the corresponding opposite button. Furthermore, to prevent magnets from slipping and to enhance their durability, a barrier is placed between the magnet and the housing. Hence, the stability of the contact portion of the button and the smooth detachment/attachment are more facilitated.
