This organopolysiloxane compound is characterized by having at least one of the unit of formula (1) as a partial structure, and being a straight chain or a branched chain. As a result, provided are: a novel ethynyl-group-containing polyorganosiloxane compound; and a method for producing a straight-chain organopolysiloxane compound containing an ethynyl group at both molecular chain ends, having superior production characteristics, and having an easily adjusted degree of polymerization. |
