ABSTRACT:
A nozzle plate includes a first thermoplastic resin film; a reinforcing plate which is formed of a material having a rigidity higher than that of the first thermoplastic resin film and which has one surface joined to the first thermoplastic resin film; and a second thermoplastic resin film which is joined to the other surface of the reinforcing plate; wherein a nozzle is formed for the first thermoplastic resin film; and through-holes, which are communicated with the nozzle, are formed through the reinforcing plate and the second thermoplastic resin film. Therefore, the nozzle plate can be produced without using any adhesive. Further, the thermoplastic resin films are joined to the both surfaces of the reinforcing plate. Therefore, any warpage is hardly caused in the reinforcing plate and the first and second thermoplastic resin films, which would be otherwise caused by the difference in coefficient of thermal expansion.
