Abstract:
1. An electronic component comprising: a first resonator having a terminal; a mounting substrate having a first principal surface, a second principal surface opposite to the first principal surface, and an electrode provided in a hole intersecting with the second principal surface; an electric connection member for electrically connecting the electrode to the terminal, and a second resonator having a band center frequency different from a band center frequency of the first resonator, said second resonator being mounted on the second principal surface, wherein one end of the electrode is provided along the second principal surface, wherein the electric connection member is provided on the one end of the electrode, wherein the first resonator is provided on the electric connection member so that the terminal is in contact with the electric connection member, and wherein the mounting substrate comprises: a phase matching circuit electrically connected to the electrode and to the second resonator; a penetrating electrode provided in a through hole extending from the first principal surface to the second principal surface, and electrically connected to the electrode on the second principal surface; and an external connection terminal provided on the first principal surface and electrically connected to the penetrating electrode on the first principal surface.
