A liquid adhesive is applied onto a surface of a base plate having flow channels formed as recesses or through-grooves, by transferring the liquid adhesive from a rotating cylinder coated with it to the surface of the base plate. The base plate is then bonded to a cover plate having ejection energy generating elements via the applied adhesive to be made into a liquid ejection head. For evenly applying the liquid adhesive onto the surface having the recesses or through-grooves as flow channels, the surface is additionally provided with dummy recesses for compensating for variance of contact length orthogonal to the transfer direction due to uneven or asymmetrical arrangement of the recesses or through-grooves. |
