A ground connection structure includes a ground terminal fitting (20) with a bolt hole (28). Resilient locking pieces (29) are formed on an inner peripheral edge of the bolt hole (28) and are locked to an externally threaded portion (13) of a stud bolt (12). A rotation stopping portion (31) is formed on the ground terminal fitting (20) and is locked to a rotation stopping hole (14) of a plate-like ground member (10). A resilient retaining piece (32) is formed on the rotation stopping portion (31) and is configured to restrict separation of the rotation stopping portion (31) from the rotation stopping hole (14) by locking to an edge part of the rotation stopping hole (14).
