Method of manufacturing electronic component package

摘要

An electronic component package includes: a main body including a plurality of layer portions that are stacked and that have their respective side surfaces, the main body having a side surface including the side surfaces of the layer portions; and wiring disposed on the side surface of the main body. Each of the layer portions has at least one electronic component chip and a plurality of electrodes disposed on the side surface of the layer portion. A method of manufacturing the electronic component package includes the steps of: fabricating a main body aggregate including a plurality of pre-main-body portions each of which is to become the main body later, the pre-main-body portions being arranged in one direction orthogonal to the direction of stacking of the plurality of layer portions; forming the wiring for each of the pre-main-body portions of the main body aggregate; and cutting the main body aggregate after the formation of the wiring so as to separate the plurality of pre-main-body portions from each other so that each of them becomes the main body and a plurality of electronic component packages are thereby formed.
