Abstract:
A thermal expandability adjuster is provided which contains a glycoluril derivative compound represented by formula (1) below. The thermal expandability adjuster can reduce the linear thermal expansion coefficient of a cured product of a thermoset resin composition used for an insulating resin layer or the like and is effective for suppressing deformation of a circuit substrate due to heating. Compounding the above thermal expandability adjuster can reduce the linear thermal expansion coefficient of a cured product obtained by curing a thermoset resin composition and it is therefore possible to provide a member that exhibits small deformation due to heat.
