Provided is a curable resin composition capable of forming an insulating adhesive layer having a necessary sufficient bonding strength and having high thermal conductivity at low cost. A curable resin composition comprising an aluminum nitride particle, an epoxy resin, a curing agent, and an acidic phosphate ester represented by the following general formula (1), wherein the respective components are mixed with each other. (Formula (1) of, R 1: a saturated hydrocarbyl group of 1 to 20 carbon atoms R 3 hydrochloride:: R 2 hydrocarbyl group of 4 to 20 carbon atoms having a carbon number of 2-3 saturated hydrocarbyl group R 4: a carbon number of 1 to 0 to 20 m: 0 to 20 n: 1 to 2, and when there are a plurality of R i (i: 1 to 4), the plurality of R i's are the same And the order of the k-COR 2 O- group, the l -R 3 O- group and the m -COR 4 COO- group is arbitrary, and when n = 2, the two side chains may be the same or different ) |
