A polymetallocarbosilane having a number average molecular weight of 700 to 100,000 derived from a polycarbosilane having a number average molecular weight of 200 to 10,000 and containing a main-chain skeleton represented mainly by the general formula <IMAGE> wherein R represents a hydrogen atom, a lower alkyl group or a phenyl group, and an organometallic compound represented by the general formula MX4 Wherein M represents Ti or Zr, and X represents an alkoxy group having 1 to 20 carbon atoms, a phenoxy group or an acetylacetoxy group, at least one of the silicon atoms of the polymetallocarbosilane being bonded to the metal atom (M) through an oxygen atom, the ratio of the total number of the structural units -Si-CH2- to the total number of the structural units -M-O- in the polymetallocarbosilane being in the range of from 2:1 to 200:1; and a process for production thereof.
