A coupling structure of a watch band in which a coupling member such as a coupling pin or a hair pin does not sup from a coupling hole even if a user practices strenuous sports or a rotation and a twist are always applied to the coupling portion due to use for years, and a method of manufacturing a piece member for the band coupling structure. In a coupling structure of a band comprising a plurality of piece members, a projection protruded in a central direction of a coupling hole from an internal wall of the coupling hole is formed on an outer end of the coupling hole in the piece member positioned on an outside in a transverse direction, and a coupling member is inserted in the coupling hole provided in the transverse direction of the piece member and is engaged with the projection, thereby coupling the piece members to each other.
