Abstract: Provided are a functional cylinder body, including a plurality of layers having magnetic patterns and non-magnetic patterns formed adjacently, and a manufacturing method therefor. The functional cylinder body comprises at least: a cylinder main body; a first functional pattern part, which includes first patterns and first functional patterns, the first patterns having first recess patterns and first non-recess patterns formed by forming recesses on a first material layer made of any one of a magnetic material and a non-magnetic material, the first functional patterns being made of any one of the magnetic material and the non-magnetic material embedded in the first recess patterns; and a second functional pattern part, which is formed in a position of the cylinder main body shallower than a position of the first recess patterns and has magnetic patterns of the magnetic material and non-magnetic patterns of the non-magnetic material formed adjacently.

Abstract: Provided are a functional cylinder body comprising magnetic patterns and non-magnetic patterns formed on a circumferential surface and a manufacturing method therefor.The functional cylinder body comprises: a cylinder body with recesses, which has recess patterns and non-recess patterns formed by forming recesses on a circumferential surface of a cylinder main body, the circumferential surface of the cylinder main body being made of any one of a magnetic material and a non-magnetic material; and functional patterns, which are made of any one of the magnetic material and the non-magnetic material and embedded in the recess patterns, in which magnetic patterns of the magnetic material and non-magnetic patterns of the non-magnetic material are adjacently formed by embedding the non-magnetic material in the recess patterns when the circumferential surface of the cylinder main body is made of the magnetic material and by embedding the magnetic material in the recess patterns when the circumferential surface of the cylinder main body is made of the non-magnetic material.

Abstract: Provided is a method of manufacturing a transfer molding roll having a fine periodic structure and a transfer molding roll, with which a continuous elongated pattern can be seamlessly formed on an object to be transferred, for example, a film. The method of manufacturing a transfer molding roll having a fine periodic structure includes: preparing a cylindrical metal base material (28); irradiating an outer circumferential surface (30) of the cylindrical metal base material with an ultrashort pulse laser; and forming a seamless circulating nano-periodic structure (34a, 34b, 34c) on the outer circumferential surface (30) of the cylindrical metal base material through irradiation of the ultrashort pulse laser to form a seamless circulating pattern (36, 38) configured to generate an optical interference color with the seamless circulating nano-periodic structure (34a, 34b, 34c).
