摘要:
A liquid discharge head includes a discharge element including a discharge port, a liquid supply port, an electric connection terminal, and a heat transfer terminal. The discharge head also includes a supporting member including an electric connection terminal portion formed on a first surface thereof and electrically connected to the electric connection terminal, a heat transfer terminal junction portion formed on the first surface and connected to the heat transfer terminal, a plurality of through-holes extending between the first surface and a second surface of the supporting member, a partition wall portion separating the through-holes from each other, and a heat transfer path connected to the heat transfer terminal junction portion. An interval between the through-holes increases according to a direction from the first surface to the second surface. A volume of the heat transfer path increases according to the increase of the interval.
