Document Type and Number:
WIPO Patent Application WO/2022/004459
Kind Code:
A1
Abstract:
When groove machining to provide a concave part 15 having a depth of 5 to 10 μm inclusive is performed in advance in a portion of a base material on which outer shape machining is to be performed and the outer shape machining is performed by a laser along the concave part 15 to manufacture a nozzle plate 10, the concave part 15 turns into a stepped part 151 and dross 152 is attached to the stepped part 151. Further, since the dross 152 is smaller than the stepped part 151, the dross 152 does not become a cause of a bonding failure or an occurrence of a void when the nozzle plate 10 is adhered to a flow path or the like.
