A nozzle plate includes: a first silicon layer; a glass layer; a second silicon layer provided between the first silicon layer and the glass layer, the second silicon layer being bonded to the glass layer; and a silicon oxide layer provided between the first silicon layer and the second silicon layer. A nozzle hole passing through the first silicon layer and discharging a droplet is formed. A channel passing through the silicon oxide layer and the second silicon layer and communicating with the nozzle hole is formed. A liquid chamber formed in the glass layer and communicating with the channel is formed.
