To provide column leg hardware and a manufacturing method for the same, for enabling efficient transmission of shearing force acting on a column leg part of a column member to base concrete and reduction in manufacturing costs by simplifying its manufacturing processes.SOLUTION: Column leg hardware 24 provided at a lower end part of a column member 5 erected on base concrete 3 comprises: a tabular base plate 26 that is formed so as to have a planar shape larger than a horizontal cross-sectional shape of the column member 5 and has a top surface on which the lower end part of the column member 5 is fixed; and a plurality of column-shaped protrusion parts 28 that are provided so as to protrude downward from a bottom surface of the base plate 26. The base plate 26 and the plurality of protrusion parts 28 are integrally molded by casting. The column leg hardware is configured so that the protrusion parts 28 are embedded inside the base concrete 3 so that lower end parts of the protrusion parts 28 are positioned below the base concrete 3's surface.SELECTED DRAWING: Figure 1
