PROBLEM TO BE SOLVED: To obtain an organometallic polymer material having high heat resistance and excellent translucency, in particular, small light propagation loss in a wavelength range of 1450 to 1550 nm. A metal alkoxide having only one hydrolyzable group and / or a hydrolyzate thereof is contained in an organometallic polymer having a —MO—M— bond (M is a metal atom). More preferably, it is an organometallic polymer material characterized by containing an organic acid anhydride and / or an organic acid. [Selection] Figure 1 |
