PROBLEM TO BE SOLVED: To provide a highly branched structure in which a siloxane bond and a silalkylene bond are alternately arranged with a polysiloxane structure as a nucleus, capable of increasing the molecular weight, and having a molecular weight distribution. A novel carbosiloxane dendrimer that is narrow and has substituents is provided. SOLUTION: General formula: X 1 R 1 a SiO (3-a) / 2 wherein R 1 is an alkyl group or an aryl group having 1 to 10 carbon atoms, and a is an integer of 0 to 2 And X 1 is i = The following equation when 1 is set And a silylalkyl group represented by ｝ Specifically, for example, A carbosiloxane dendrimer having a polysiloxane structure having two or more silicon atoms containing a siloxane unit represented by the formula: |
