Claim 0:
1. A liquid discharge head comprising:
piezoelectric elements;
a vibrating plate disposed at a position below the piezoelectric elements in a first direction; and
a pressure chamber plate disposed at a position below the vibrating plate in the first direction, the pressure chamber plate having a partition wall defining pressure chambers, wherein
in the respective pressure chambers, when one of two positions in a second direction intersecting the first direction is defined as a first position and the other position is defined as a second position from which the shortest distance to the partition wall is shorter than the shortest distance from the first position to the partition wall,
the vibrating plate has a first portion corresponding to the first position and a second portion corresponding to the second position,
a surface of the first portion in the first direction is, in the first direction, closer than below a surface of the second portion in the first direction,
a thickness of the first portion in the first direction is greater than a thickness of the second portion in the first direction.
