To make attachment of a permanent magnet, a ceramic plate, etc., easy and efficient and make attachment thereof complete without using a resin film, metal fittings, etc., when the permanent magnet, the ceramic plate, etc., are attached to a fine-width fabric.

In the fine-width woven fabric forming a base part of magnetic therapy device, etc., used in a form of shoulder straps of brassiere, a supporter, waist belt, etc., a double woven fabric having a required fine width is formed by inside and outside double structures and the inside and outside structures are mutually connected by a structure-forming yarn and the inside and outside structures are mutually connected by a structure-forming yarn on one side of a longitudinal direction of the woven fabric and the inside and outside structures are mutually connected by the structure-forming yarn in a width direction at an adequate interval in the longitudinal direction. As a result, many pockets having openings 5 on other side of the woven fabric are continuously formed by both connecting parts.
