Patent ID: 7293860

Claim:
A droplet ejecting head including a nozzle plate through which are formed a plurality of nozzle holes each for ejecting a droplet therethrough, each of the nozzle holes comprising: a jetting end which is open at a first one of opposite surfaces of the nozzle plate; an inflow end which is open at a second surface of the nozzle plate; a taper portion between the jetting end and a vicinity of the inflow end, at the taper portion a diameter of the nozzle hole linearly increasing from the jetting end to the vicinity of the inflow end so that the taper portion has a taper angle; a connecting portion comprising a surface connecting an end of the taper portion and the inflow end, at the connecting portion the diameter increasing more greatly than at a surface which is obtained if the taper portion is extended at the taper angle; and where D 1 and D 2 respectively represent the diameter of the nozzle hole at the inflow end and at an imaginary inflow end which is obtained if there is not the connecting portion and the taper portion extends at the taper angle up to the second surface, D 1 being larger than D 2 but smaller than 1.2×D 2 .
