There is provided a metallic male snap part (1) capable of enhancing coupling strength with a female snap part (3) by giving appropriate and sufficient elastic deformability to the projection (20) of the male snap part (1) which can be coupled to a depression (50) of the female snap part (3). The projection (20) includes a plurality of relatively highly deformable portions (26a) and a plurality of relatively low deformable portions (26b), the highly and low deformable portions being arranged alternately in the circumference direction of the projection (20). The highly deformable portions (26a) are more deformable elastically in the radial direction of the projection (20) than the low deformable portions (26b). Each of the highly deformable portions (26a) has a relatively large, outer bulge (24a) which bulges more outward in the radial direction than a relatively small, outer bulge (24b) of each of the low deformable portions (26b). The projection (20) further includes longitudinal slits (25) and lateral slits (27) to partition the projection (20) into the highly deformable portions (26a) and the low deformable portions (26b).
