A FISHING REEL HANDLE ASSEMBLY (2) HAS A HANDLE ARM (21), A KNOB SHAFT (22), AND A HANDLE KNOB (23). THE HANDLE ARM (21) IS RELATIVELY NON-ROTATABLY ATTACHED TO A DISTAL END OF THE HANDLE SHAFT (20). THE KNOB SHAFT (22) IS FIXED TO AN END OF THE HANDLE ARM (21) AND EXTENDS IN PARALLEL TO THE HANDLE SHAFT (20). THE HANDLE KNOB (23) IS SUPPORTED BY THE KNOB SHAFT (22) TO BE ROTATABLE RELATIVE TO THE HANDLE ARM (21). THE HANDLE ARM (21) INCLUDES A MAIN BODY (21A) AND A CONVEXO-CONCAVE PORTION (21B, 21C). THE MAIN BODY (21A) EXTENDS SUBSTANTIALLY PERPENDICULAR TO AN AXIAL DIRECTION OF THE HANDLE SHAFT (20), AND IS FORMED BY LAMINATING SHEETS OF PREPREG (30). THE CONVEXO-CONCAVE PORTION (21B, 21C) IS CONVEXLY OR CONCAVELY FORMED ON AT LEAST EITHER A FRONT SURFACE OF THE MAIN BODY (21A) OR A BACK SURFACE OF THE MAIN BODY (21A). THE FRONT SURFACE ALLOWS THE HANDLE KNOB (23) TO BE ATTACHED THERETO, THE BACK SURFACE DISPOSED OPPOSITE TO THE FRONT SURFACE. (FIG. 1)
