A rotor (3) for a spinning reel is configured to rotate about a spool shaft (15), and includes a tubular portion (29) and a plate-shaped portion (50). The tubular portion (29) is disposed away from the spool shaft at a predetermined interval. The plate-shaped portion (50) includes a radially outer part (51) and a radially inner part (52). The radially outer part (51) is integrated with an inner peripheral part of the tubular portion (29). The radially inner part (52) extends from the radially outer part (51) toward the spool shaft (15). The radially outer part (51) has a smaller thickness than at least a part of the radially inner part (52).
