Abstract: Provided is a polyorganosilsesquioxane that is suitable as a material for a hard coat film or an adhesive, the polyorganosilsesquioxane being capable of forming a cured product having a high surface hardness and flexibility while having a high heat resistance or the like. The polyorganosilsesquioxane contains a cage-type silsesquioxane represented by Compositional Formula (1). When the polyorganosilsesquioxane is analyzed using a liquid chromatography-evaporative light scattering detector, a peak area % of the cage-type silsesquioxane represented by Compositional Formula (1) is 5% or greater with respect to a peak area of all components detected.
