It is an object of the invention to provide an electronic device in which a passive element with an excellent element characteristic is embedded and a method of manufacturing the same. It is another object of the invention to provide an electronic device which makes miniaturization thereof possible and a method of manufacturing the same. A body (10) and a functional block (30) are stuck together by accommodating the functional block (30) in an opening of green ceramic sheets and then sintering those sheets. A temperature for sintering sheets to constitute a dielectric portion (31) of the functional block (30) can be different from that for sintering a raw material of a ceramic material to constitute a dielectric portion (12) of the body (10). Flexibility in selecting a material of the dielectric portion (31) can be extended and a material with a low dielectric constant can be selected for the dielectric portion (31). A dielectric constant of the ceramic material of the functional block (30) can be higher to realize miniaturization of the functional block (30). Since conductor patterns of the functional block (30) can be formed by means of thin film technologies, a three-dimensional appearance is given to edges of the conductor patterns, thereby the functional block (30) with a high Q-value can be embedded in the body (10).
