A surgical implant comprises an areal, flexible, mesh-like basic structure (2) including a knitted fabric made in gallon crotcheting technique, in which mesh pores (4) are formed from chains (10) made in closed pillar stitch. Adjacent chains (11, 11&prime) are connected to each other, by at least one inlaying weft thread (16, 18), in sections forming a respective common side (12) of two adjacent mesh pores (14, 14&prime). The inlaying weft thread (16, 18), in the region of said common side (12), runs in at least three loop courses (17, 17&prime, 17&Prime, 19, 19&prime, 19&Prime).
