PURPOSE:To obtain a liquid jet recording apparatus good in frequency characteristics in the emission of liquid droplets and capable of enhancing a recording speed, by rapidly performing the re-replenishment of a liquid by providing a auxiliary liquid supply port. CONSTITUTION:Gaps, which are respectively auxiliary liquid supply ports, are provided not only between a side wall 202 and an orifice plate 205 but also between the side wall 202 and a substrate 201. The re-replenishment of a liquid is performed ont only from the liquid flowline corresponding to one orifice 204 but also from the above mentioned gaps while the loss of power inherent to energy for forming liquid droplets in a flight state is reduced as possible to achieve the performance of rapid liquid replenishment. In the typical obliquely viewed partial drawing, the part where coarse oblique lines are applied to the upper end part of a side wall 302 is a part to which an orifice plate 305 is closely adhered and a part to which the oblique lines are not applied comes to a gap part. The position of the gap part is pref. provided in the vicinity of a heat generating part and, when provided in a liquid flowline, more pref. provided to the opposite side of the orifice. The gap provided to the side wall can enhance a max. frequency limit to a large extent. |
