Abstract
A multi-piece solid golf ball comprising a rubbery elastic core and a cover enclosing the core and consisting of a plurality of resinous layers is provided. Among the plurality of cover layers, the outermost layer has a thickness of less than 1 mm and a Shore D hardness of 50-65 and an inner layer has a thickness of 0.5-2.0 mm and a Shore D hardness of 40-55. The ball is easy to control due to high-spin receptivity when hit with a short iron, and travels a distance due to restricted spin when hit with a small loft club like driver.
