Abstract
A liquid discharging head includes: a first common channel, a second common channel, and individual channels aligned in a first direction. Each of the individual channels has: a nozzle, a pressure chamber, a descender formed in a channel substrate which is formed of silicon and which is arranged between a nozzle plate and a pressure chamber plate in a second direction orthogonal to the first direction; and a connecting channel which is formed in the channel substrate. The second common channel is formed in the channel substrate. The descender penetrates the channel substrate in the second direction, and has an inner wall surface parallel to the second direction and to a third direction orthogonal to both of the first direction and the second direction. The connecting channel extends in a fourth direction which is orthogonal to the second direction and which is inclined with respect to the third direction.
