A method of manufacturing an electronic component having a concave portion. A ceramic laminate is prepared having a plurality of sheets with burnaway film formed thereon. The burnaway film material is capable of being burned away by firing. The burnaway film is provided in layers in positions corresponding to the desired position of the concave portion. Firing the ceramic laminate burns out the burnaway film, and a sintered body is formed with a plurality of cavities provided in layers between a plurality of thin laminate layers. Crushing the thin layers of the sintered body forms the concave portion.
