A method for manufacturing a woven fabric, the woven fabric including fiber warp threads and fiber weft threads, and further including flat threads each wider than each fiber warp thread, the method comprising: causing the flat threads to pass through healds intermittently with respect to a plurality of the fiber warp threads; causing each flat thread to pass through a hole of the heald corresponding thereto, the hole being long in a heald moving direction, thereby to orient a longitudinal direction in transverse plane of the flat thread along the heald moving direction; interweaving the fiber weft threads with the fiber warp threads to form a plurality of woven fabric placement sections so as to be arranged in a weft direction, each woven fabric placement section being formed as a woven fabric structure and having the flat thread corresponding thereto placed on the woven fabric structure; disposing a flat face of the flat thread on the fiber warp threads in the woven fabric placement section so as to face the fiber warp threads; and causing a part of the fiber weft threads to pass over the flat thread, to fix the flat thread on the woven fabric placement section. the woven fabric including fiber warp threads and fiber weft threads, and further including flat threads each wider than each fiber warp thread, the method comprising: causing the flat threads to pass through healds intermittently with respect to a plurality of the fiber warp threads; causing each flat thread to pass through a hole of the heald corresponding thereto, the hole being long in a heald moving direction, thereby to orient a longitudinal direction in transverse plane of the flat thread along the heald moving direction; interweaving the fiber weft threads with the fiber warp threads to form a plurality of woven fabric placement sections so as to be arranged in a weft direction, each woven fabric placement section being formed as a woven fabric structure and having the flat thread corresponding thereto placed on the woven fabric structure; disposing a flat face of the flat thread on the fiber warp threads in the woven fabric placement section so as to face the fiber warp threads; and causing a part of the fiber weft threads to pass over the flat thread, to fix the flat thread on the woven fabric placement section. causing the flat threads to pass through healds intermittently with respect to a plurality of the fiber warp threads; causing each flat thread to pass through a hole of the heald corresponding thereto, the hole being long in a heald moving direction, thereby to orient a longitudinal direction in transverse plane of the flat thread along the heald moving direction; interweaving the fiber weft threads with the fiber warp threads to form a plurality of woven fabric placement sections so as to be arranged in a weft direction, each woven fabric placement section being formed as a woven fabric structure and having the flat thread corresponding thereto placed on the woven fabric structure; disposing a flat face of the flat thread on the fiber warp threads in the woven fabric placement section so as to face the fiber warp threads; and causing a part of the fiber weft threads to pass over the flat thread, to fix the flat thread on the woven fabric placement section.
