The present invention provides a multi-piece solid golf ball having excellent flight performance and good shot feel. The present invention relates to a multi-piece solid golf ball comprising a core consisting of an inner core, an intermediate layer and an outer layer, and a cover, wherein the inner core has a flexural rigidity (RI) of 20 to 80 MPa, a ratio (RM/RI) of a flexural rigidity of the intermediate layer (RM) to the (RI) is from 0.6 to 1.4, a flexural rigidity of the outer layer is higher than the (RI) by 70 to 500 MPa, and the intermediate layer is placed such that the a radius of the golf ball (rG), a radius of the inner core (rI) and a radius of a two-layer structured core obtained by forming the intermediate layer on the inner core (rT) satisfy the following two formulae: rI/rG>=0.70 rT/rG<=0.83
