It is an object of the present invention to reduce the weight of a support member (40) and inhibit cost increase in a spinning reel fishing line guide mechanism (44). A spinning reel fishing line guide mechanism (44) for guiding a fishing line onto a spool (4) includes a support member (40) and a fixation member (45). The spinning reel fishing line guide mechanism (44) is attached to a tip of a rotor arm (31) and is pivotable between a fishing-line guide position and a fishing-line release position. The support member (40) is attached pivotably to the tip of the rotor arm (31). The support member (40) includes an outer member (91) made of metal and an inner member (92) made of synthetic resin. The inner member (92) is fixed to an inner surface of the outer member (91). Fig. 3
