A composite monolithic electronic component has a laminate including a base layer having a relative dielectric coefficient of about 10 or less and a functional layer which is at least one of a high-dielectric-coefficient layer having a relative dielectric coefficient of about 15 or more and a magnetic layer. The base layer contains a crystallized glass containing SiO2, MgO, Al2O3 and B2O3, and a ceramic oxide having a thermal expansion coefficient of about 6.0 ppm/.degree.C. or more. The functional layer contains an amorphous glass having a softening point of about 800.degree. C. or less.
