Electronic chip component

摘要

A band-pass filter functioning as a electronic chip component includes a chip having upper and lower surfaces, a pair of side surfaces, and first and second end surfaces facing each other. A resonator electrode is disposed in the chip. The band-pass filter also includes input and output electrodes extending in the vertical direction, which are coupled or connected to the resonator electrode, and a tubular first ground electrode surrounding the chip so as to enclose the resonator electrode. The input and output electrodes are disposed at end portions or inner sides of the tubular portion so as not to be electrically connected to the first ground electrode. The band-pass filter further includes two pairs of second ground electrodes which are disposed on both sides of the input electrode and/or output electrode and which are electrically connected to the first ground electrode.
