Abstract
A liquid discharge head includes a member which is provided with a discharge port for discharging a liquid and made of a resin. Here, the member contains a plurality of inorganic particles. In addition, in a surface of the member on which the discharge port is opened, a density of the particles in a circumference of the discharge port is higher than that of the particles in the vicinity thereof.
Claims9
A liquid discharge head comprising:
- a member which is provided with a discharge port for discharging a liquid and made of a resin,
- wherein the member contains a plurality of inorganic particles, and
- wherein in a surface of the member on which the discharge port is opened, a density of the particles in a circumference of the discharge port is higher than that of the particles in the vicinity thereof.
A method of manufacturing a liquid discharge head which includes a member provided with a discharge port for discharging a liquid, the method comprising:
- providing a layer on a substrate, the layer being used for forming the member and being made of a composition containing a polymerizable resin, a photo-polymerization initiator, and a plurality of inorganic particles;
- exposing a portion of the layer such that a portion to be exposed surrounds a portion not to be exposed on a surface of the layer, and hardening the portion of the layer on which the exposure is carried out;
- and
- exposing an edge of the portion on which the exposure is not carried out so as to harden the edge and removing the portion of the layer on which the exposure is not carried out so as to form the discharge port.
