A method of manufacturing a liquid ejection head, includes forming a first substrate into a curved shape so as to form a portion of a substantially cylindrical shape, the first substrate being provided with a liquid flow channel of liquid and a drive wire for supplying a drive signal to a piezoelectric element; forming a second substrate into a curved shape so as to form a portion of a substantially cylindrical shape, the second substrate forming a pressure generating chamber for ejecting the liquid and a diaphragm which forms a surface of the pressure generating chamber; forming the piezoelectric element on the diaphragm at a position corresponding to the pressure generating chamber; forming an ejection port plate on an opposite side across the pressure generating chamber from the diaphragm; and bonding together the first substrate and the second substrate.
