    摘要： A gradient-index rod lens is provided that is excellent in yield. The gradient-index rod lens has a core/clad structure and is obtained by providing a mother glass rod, which includes a core glass mother composition and a clad glass mother composition, with a refractive index distribution through ion exchange. The clad and the core each contains an alkali metal oxide but are substantially free from lead. The clad and the core each contains an alkali metal oxide and has a basic composition including components other than the alkali metal oxide, but they are different from each other in the basic composition. The clad glass mother composition has a higher thermal expansion coefficient and glass-transition temperature than those of the core glass mother composition. The difference of the thermal expansion coefficient between the clad glass mother composition and the core glass mother composition is larger than 2×10−7/° C. but smaller than 20×10−7/° C.

In the clad glass composition, at least two molar ratios selected from the group consisting of: MgO/(MgO+CaO+SrO+BaO); CaO/(MgO+CaO+SrO+BaO); SrO/(MgO+CaO+SrO+BaO); and BaO/(MgO+CaO+SrO+BaO) are at least 0.1. The clad glass composition is substantially free from lead and has a refractive index in the range of 1.56 to 1.68.
