PURPOSE: To divide the button into a fitting part to clothes and a surface part having decorative face, so that the surface part can be attached and detached simply, and can be replaced with other plural surface parts.

CONSTITUTION: The button is divided through a screw 3 into a surface part 1 being the decorative face, and a fixed part 2 containing a fitting part 4 to be attached to clothes. The surface part 1 can be detached with the screw 3 from the fixed part 2, and the fixed part 2 remains behind on the clothes side. In the case it is desired to change to a different button, a different kind surface part 1 of the same structure is screwed in and attached. By replacing simply the surface part of the botton clothes, fashionability of clothes can be enlarged and enjoyed easily.
