    Abstract: Provided is an adhesive composition that can be cured at low temperatures and can form a cured product having excellent insulating property, heat resistance, and adhesiveness. The adhesive composition according to the present invention includes polyorganosilsesquioxane (A) including a constituent unit represented by Formula (1) below, R1SiO3/2(1), in Formula (1), R1 represents a group containing a radically polymerizable group. In the polyorganosilsesquioxane (A), a proportion of the constituent unit represented by Formula (1) and a constituent unit represented by the following Formula (2), relative to a total amount (100 mol %) of siloxane constituent units, is from 55 to 100 mol %, R1SiO2/2(OR2) (2), in Formula (2), R1 is as defined above, and R2 is a hydrogen atom or an alkyl group having from 1 to 4 carbons. The polyorganosilsesquioxane (A) has a number average molecular weight from 1500 to 50000 and a molecular weight dispersity (weight average molecular weight/number average molecular weight) from 1.0 to 4.0.
