A method of manufacturing a capacitor-embedded low temperature co-fired ceramic substrate. A capacitor part is manufactured by firing a deposition including at least one high dielectric ceramic sheet to form a capacitor part. A plurality of low temperature co-fired green sheets are provided. Each of the low temperature co-fired green sheet has at least one of a conductive pattern and a conductive via hole thereon. A low temperature co-fired ceramic deposition is formed by depositing the low temperature co-fired green sheets to embed the capacitor part in the low temperature co-fired ceramic deposition. The embedded capacitor part is connected either to the conductive pattern or the conductive via hole of an adjacent green sheet. Then the low temperature co-fired ceramic deposition having the capacitor part embedded therein is fired.
