摘要： A pressing method by which through holes are formed using a punch in a target plate material that has a first face and a second face that is opposite to the first face, includes forming at least one first through hole by punching the target plate material from the second face with the punch in such an orientation that the first face of the target plate material is in contact with a base that is made of an elastic material, and forming at least one second through hole from the first face of the target plate material in a region, which is different from a region in which the at least one first through hole is formed, in such an orientation that the second face of the target plate material is in contact with the base.

摘要： There is provided a filter having a plate-like shape in which a plurality of holes through which fluid passes is opened. A low opening region in which an aperture ratio of the holes per unit area is low and a high opening region in which an aperture ratio of the holes per unit area is high are formed in the filter.

摘要： A die apparatus is composed of a lower receiving die, a round punch having the shape of a fine hole, and PET provided between the lower receiving die and the round punch. The round punch is passed through a work plate placed on the PET to cause a punched-out piece to remain within the PET, thereby boring the fine hole. The work plate having such fine holes is thus easily prepared, and applied as a filter for a liquid-jet head.
