Zusammenfassung:To propose a machined article having a precisely-machined slit of minute dimensions and a pressing method capable of easily and precisely machining the slit of minute dimensions. A machined article 100 includes a first member 101 including an inner peripheral portion 101a formed by a hole, and a second member including an outer peripheral portion 102a fitted into the inner peripheral portion 101a of the first member 101. At least either an inner peripheral recess 101b to be formed in part of the inner peripheral portion 101a of the first member 101 or an outer peripheral recess 102b to be formed in part of the outer peripheral portion 102a of the second member 102 is formed. A slit 103 penetrating from a front to a back is formed at a position to which the inner peripheral recess 101b or the outer peripheral recess 102b corresponds, between the first member 101 and the second member 102.
