PROBLEM TO BE SOLVED: To provide a laminated chip coil capable of attaining both excellent DC superimposition characteristics and low resistance at a high inductance value. SOLUTION: The laminated chip coil includes a first magnetic substance 3 made of a ferrite sintered body, inner conductors 5a-5d buried in the first magnetic substance 3 and having a predetermined pattern formed, and a terminal electrode connected with ends of the inner conductors 5a and 5d and provided on the first magnetic substance 3. A through-hole 4a passing through the first magnetic substance is formed on the first body 3 in such a range that the inner conductors 5a-5d are not exposed. A second magnetic substance 3 is placed in the through-hole 4a, and thus both the excellent DC superimposition characteristics and low resistance can be attained at a high inductance value.
