摘要： A piezoelectric resonator adapted to generate a third harmonic wave of a thickness extensional vibration mode in which the fundamental wave is lead out of the vibrating portion and suppressed effectively. The piezoelectric resonator includes a vibrating portion with vibration electrodes opposing each other in the middle of a piezoelectric plate, lead-out electrodes electrically connected to the vibration electrodes, and a floating electrode disposed along the short side edge on at least one major surface of the piezoelectric plate or in the vicinity of the edge.

摘要： A surface mounting structure is arranged to minimize a height dimension of an electronic component. A surface mount type electronic component is provided on the surface mounting structure. The surface mount type electronic component includes a piezoelectric component element including an insulating substrate, and a piezo-resonator mounted on a mounting surface of the insulating substrate. The piezoelectric component element is mounted on a printed circuit board, with the mounting surface being arranged to face a surface of the printed circuit board. A recess is formed in the printed circuit board and a portion of the piezoelectric component element is accommodated in the recess. A conductive adhesive is located on external connection electrodes provided on the mounting surface and is firmly attached to circuit patterns on the printed circuit board so that the piezoelectric component element is fixed to the printed circuit board. Further, the external connection electrodes are electrically connected to the circuit patterns.

摘要： An electronic component is constructed to prevent damage and stripping off or separation at adhered portions thereof even if the component is exposed to abrupt temperature changes to thereby provide a highly reliable component. A piezoelectric vibrating element defining a first substrate and an electronic component case including a pair of substrates which are second substrates are adhered together through an adhesive layer so as to define a closed space. The adhesive layer includes a fillet portion which is arranged to extend along lateral walls of the recess to edges of the closed space to prevent separation at adhesion interface surfaces of the substrates.
