An inorganic glass having high water repellence produced by irradiating and/or implanting ions upon or into a surface of the inorganic glass, the ions are those of at least one element selected from the group consisting of (a) halogen elements selected from F, Cl, and Br, group 3A, 3B, 4A and 5B elements of the International Periodic Table selected from Al, Ti, Y, In and Bi, (b) rare gas elements selected from He, Ne, Ar, Kr and Xe, group 3A, 4A, 1B, 2B, 3B, 4B and 5B elements of the International Periodic Table selected from Sc, Cu, Zn, Ag, Cd, Sn, Sb, Au, Hg, Tl and Pb, alkali metal or alkaline earth metal elements selected from Li, Na, K, Rb, Cs, Be, Mg, Ca, Sr and Ba, and (c) Ce, the dose of th (a), (b) and (c) ions being 5x1014 to 1x1020 ion/cm2, 5x1014 to 1x1017 ion/cm2 and 1x1017 to 1x1020 ion/cm2, respectively.
