Abstract
A multi-layer piezoelectric ceramic component includes: a piezoelectric ceramic body having a cuboid shape having upper and lower surfaces facing in a thickness direction, first and second end surfaces facing in a length direction, and a pair of side surfaces facing in a width direction; first internal electrodes formed in the piezoelectric ceramic body and drawn to the first end surface; second internal electrodes formed in the piezoelectric ceramic body and drawn to the second end surface; a first terminal electrode formed on the first end surface; and a second terminal electrode formed on the second end surface, the first and second internal electrodes each having a width equal to a distance between the pair of side surfaces, at least one of the pair of side surfaces including a groove extending in non-parallel with the length direction.
