Electronic component

An energy trap type piezoelectric resonator, comprising:

• a piezoelectric member having an upper surface, a lower surface, a pair of side surfaces opposed to each other, and a pair of first and second end surfaces opposed to each other, the pair of side surfaces extending in the longitudinal direction of the piezoelectric member and being opposed to each other in the width direction of the piezoelectric member;
• first and second resonance electrodes provided on the upper and lower surfaces of the piezoelectric member, respectively, the first resonance electrode extending from an edge defined by the first end surface and the upper surface toward the second end surface, the second resonance electrode extending from an edge defined by the second end surface and the lower surface toward the first end surface, the first and second resonance electrodes being arranged to overlap each other at an approximate center of the piezoelectric member in the longitudinal direction;
• a flat plate-shaped first inner electrode layer exposed at the upper surface at a desired region in the width direction of the piezoelectric member, said first inner electrode layer being spaced inwardly from said pair of end surfaces, said first inner electrode layer extending from the upper surface toward the lower surface, said first inner electrode layer being exposed at the lower surface at a desired region in the width direction of the piezoelectric member, and said first inner electrode layer being electrically connected to the first or second resonance electrode;
• and
• a connecting electrode provided on the upper or lower surface of the piezoelectric member and electrically connected to the inner electrode layer;
• wherein
• said first inner electrode layer is spaced inwardly from said pair of first and second end surfaces such that piezoelectric material of the piezoelectric member is interposed between the first inner electrode layer and said pair of first and second end surfaces.
