摘要：
Provided are a stacked electronic part that can sufficiently suppress plating deposition on the surface of a porous green body when a terminal electrode is formed on an external electrode, thereby enabling a decrease in the reliability of products to be prevented, and a method of manufacturing the stacked electronic part. The stacked electronic part 1 is a PTC thermistor having a stacked body 4 containing a porous green body 2 made of ceramics and having a plurality of vacancies and a plurality of internal electrodes 3 formed within the porous green body 2, and is provided with at least one unit structure 10 in which the porous green body 2 and the internal electrode 3 are stacked. External electrodes 5, 5 are connected to the internal electrode 2, and upon the external electrodes 5, 5 are formed terminal electrodes 7, 7 by plating. Resin is filled in the plurality of vacancies of the porous green body 2 at a filling ratio of not less than 60%.
