    摘要： A piezoelectric material includes a PZT ceramic, and a noble metal component. The noble metal component is added to the PZT ceramic in an amount of 0.35 parts by volume or more with respect to 100 parts by volume of the PZT ceramic, and is at least one element selected from the group consisting of Ru, Rh, Pd, Os, Ir, Pt and Au, or is an alloy of silver (Ag) and the noble metal element. A piezoelectric element includes a pair of external electrodes, at least a pair of piezoelectric layers, and a conductive layer. The piezoelectric layers are formed of the PZT ceramic, and are disposed between the external electrodes. The conductive layer is formed of the noble metal component, and is insulated from the external electrodes. The piezoelectric layers and the conductive layer are formed lamellarly, and are laminated alternately in a direction connecting the external electrodes.

    摘要： The present invention provides a speaker mounting structure that takes up less space and affords easier mounting. A mounting component 6 of a speaker 2 is provided to the rear pillar 3 of an automobile 1. A quarter inner panel 7 is provided on the interior IN side of this speaker mounting component 6, and a side body outer panel 8 is provided on the exterior OUT side, leaving a specific gap 9 in between. An extension panel 10 is attached on the exterior side OUT of the quarter inner panel 7. A through-hole 14 is formed in the quarter inner panel 7 and the extension panel 10, and the rear end 12 of the speaker 2 is inserted into the through-hole 14. As a result, the speaker 2 is moved further to the exterior OUT of the cabin, so the trim piece 16 does not protrude as far into the interior IN and rearward visibility is improved.
