PROBLEM TO BE SOLVED: To provide a ceramic laminate wherein a sintered ferrite layer and a glass ceramic layer are properly bonded together, and to provide an electronic device. SOLUTION: The ceramic laminate 4 includes: a glass ceramic sintered compact 41 containing an amorphous glass component and a first crystal; and a ferrite sintered compact 42 containing a ferrite crystal and bonded to the glass ceramic sintered compact 41. An intervening layer 43 containing an amorphous glass component and a second crystal is formed between the glass ceramic sintered compact 41 and the ferrite sintered compact 42. The second crystal has the same crystal structure as the ferrite crystal and the first crystal, and the difference of lattice constant between the second crystal and the ferrite crystal and the difference of lattice constant between the second crystal and the first crystal are 10% or less of the lattice constant of the second crystal, respectively, and further the amorphous glass component is contained in the intervening layer 43 by the proportion of 10-50 mass%. Peeling of the sintered ferrite layer 42 from the glass ceramic layer 41 is reduced. COPYRIGHT: (C)2011,JPO&INPIT
