ABSTRACT:
A multilayer electronic component has: a first capacitive electrode layer of a rectangular shape on which four capacitive electrode portions are formed at four comers; and a ground electrode layer which is laid on the first capacitive electrode layer and on which a ground electrode is formed so as to be arranged as superposed over the four capacitive electrode portions. The four capacitive electrode portions are equidistant from a first facing edge pair of the first capacitive electrode layer and equidistant from a second facing edge pair different from the first edge pair. This configuration equalizes distributions of electric fields established between the respective capacitive electrode portions and the ground electrode, which realizes uniformization of the capacitances in the four respective capacitive electrode portions.
