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. L'invention concerne un composé organopolysiloxane caractérisé par au moins une unité de formule (1) en tant que structure partielle, et étant une chaîne linéaire ou une chaîne ramifiée. Ainsi, l'invention concerne : un nouveau composé polyorganosiloxane contenant un groupe éthynyle; et un procédé de production d'un composé organopolysiloxane à chaîne linéaire contenant un groupe éthynyle aux deux extrémités de la chaîne moléculaire, ayant d'excellentes caractéristiques de production, et ayant un degré de polymérisation facilement ajusté.
