Abstract:
A piezoelectric vibration component and a portable terminal each include a piezoelectric vibration element 14 and a power supply line 51. The piezoelectric vibration element 14 includes at least: a layered structure 20 in which a plurality of internal electrodes and piezoelectric layers are layered in a first direction; and surface electrodes 33 and 31 electrically connected to the internal electrodes. The piezoelectric vibration element 14 bends and vibrates, and its amplitude changes in a second direction perpendicular to the first direction. The power supply line 51 includes at least: a conductive path 53 including a connection part 56 bonded to a surface electrode 33; and a conductive path 52 including a connection part 57 bonded to a surface electrode 31. The connection part 56 has a plurality of partial electrodes 56a and 56b that extend in a third direction perpendicular to both the first direction and the second direction.
