Method for manufacturing linear member

Abstract

A method for manufacturing a linear member reduces changes in the physical properties of a substance serving as a material for the linear member that may be caused when the substance is formed into a linear shape from powder. A manufacturing device usable for the method for manufacturing a linear member is a device for manufacturing a linear member having a predetermined function. The device includes a compressor. The compressor compresses, from an outer periphery of an elongated hollow body (9), the hollow body (9) accommodating powder of a substance having the predetermined function at an inner periphery of the hollow body (9) to compact the powder to allow the powder to substantially show the predetermined function. The linear member can be freely deformed while linearly accommodating the powder and maintaining the powder compacted. This structure can reduce changes in the physical properties of a substance in the linear member having the predetermined function that may be caused when the substance is formed into a linear shape from the powder.
