PROBLEM TO BE SOLVED: To provide a device for machining and holding a polyhedron and a machining method capable of accurately machining the polyhedron having side faces connected to horizontal upper and lower surfaces, respectively, at the same predetermined angle in less machining processes without using a dedicated machining device. SOLUTION: This device is constituted of a piece member 40 having first holding part 41 and second holding part 42 attachably/detachably holding two adjacent side surfaces of a material 20 to be machined, and a piece holding member 50 having an attaching and fixing part 51 for attachably/detachably attaching and fixing the piece member 40 and having a horizontal holding part 55 held by the piece member 40 attached and fixed to the part 51 and for horizontally holding so that a face of the material 20 facing upward or downward or both upper and lower faces are to be surfaces K to be finish-machined.
