The invention provides chain belts and a chain belt pattern forming method. In a chain belt (2, 2a, 32) of the invention, a pattern visible surface of a cloth belt (4, 34a) is configured with a transparent thin film layer (21), a belt opposite surface of the thin film layer (21) is formed with an ink pattern portion (22, 26) formed by fixing ink. A belt opposite surface of the ink pattern portion (22, 26) is configured with a pigment layer (23) containing a pigment. A pattern non-forming region, having no ink pattern portion (22, 26), of the thin film layer and the pigment layer (23) are bonded to the cloth belt (4, 34a) through an adhesive layer (24). Thus, a printed pattern can be beautifully and stably attached to the pattern visible surface of the cloth belt (4, 34a) without being deformed, and the color of the ink pattern portion (22, 26) of the printed pattern can be less susceptible to the color of the cloth belt (4, 34a) and can be clearly displayed.
