The invention provides a multi-piece solid golf ball composed of a solid core, a cover, at least one intermediate layer situated therebetween, and a plurality of dimples on a surface of the ball. The diameter of the solid core, the deflection of the core when compressed under a final load of 130 kgf from an initial load of 10 kgf, the hardness at the center of the core, the hardness in a region 5 mm to 10 mm from the center of the core, the hardness 15 mm from the center of the core, and the surface hardness are set within specific ranges. The intermediate layer is composed primarily of a material obtained by mixing under applied heat a specific resin composition, and the thickness and material hardness of the intermediate layer, as well as the hardness difference between the surface of the solid core and the intermediate layer are set within specific ranges. The cover is formed primarily of polyurethane, and has a thickness and a material hardness set within specific ranges. The golf ball of the invention has an excellent flight performance, feel, controllability and scuff resistance.
