Abstract
A recording element board includes a discharge orifice configured to discharge liquid, a pressure chamber communicating with the discharge orifice, a recording element configured to generate thermal energy to cause bubbling of the liquid, the recording element being disposed in the pressure chamber facing the discharge orifice, and a substrate on which the recording element is formed. When the recording element is driven and the liquid of within the pressure chamber is discharged, a generated bubble communicates with the atmosphere. A discharge orifice projection region where the discharge orifice has been projected on the substrate includes a region includes a region extending beyond a heat-generating region projection region where the heat-generating region of the recording element has been projected on the substrate, the outline of the discharge orifice projection region is circumscribed by the outline of the heat-generating region projection region.
