Provided is a method for manufacturing a lightweight fishing line guide which has a guide ring for guiding the fishing line, and is attached to a tubular rod. This method for manufacturing a fishing line guide includes: a step for producing a ring support (1300) that holds and supports a guide ring (1200)； and a step for injection-molding an annular attachment part (1100) having an inner circumferential surface (1112) fitted to the outer circumferential surface of a tubular rod (113). The ring support (1300) is composed of a thin metal sheet. The ring support (1300) includes a ring holding part (1310) that holds the guide ring (1200)； and a ring support part (1320) integrally formed with the ring holding part (1310). The ring support part (1320) is bent at a first bending angle (BA1) with respect to a first bent part (1331) that extends down to the lower end of the ring support part (1320) in a downward direction toward the tubular rod (113). The attachment part (1100) is injection-molded from a resin material by using the ring support (1300) as an insert so that a portion of the lower side of the ring support part (1320) is embedded in the attachment part (1100), said portion of the lower side of the ring support part (1320) including a portion of the lower side of the first bent part (1331).本發明提供一種具有對釣線進行引導之導引環且安裝於釣竿之管狀竿之輕量之釣線導引件之製造方法。釣線導引件之製造方法包含：對保持並支持導引環(1200)之環支架(1300)進行加工之階段、及將具有與管狀竿(113)之外周面嵌合之內周面(1112)之環狀安裝部(1100)射出成形之階段。環支架(1300)包含金屬製之薄板。環支架(1300)包含保持導引環(1200)之環保持部(1310)、及與環保持部(1310)一體形成之環支持部(1320)。環支持部(1320)以於朝管狀竿(113)之下方方向延長至環支持部(1320)之下端之第1彎曲部(1331)為基準，以第1彎曲角(BA1)彎曲。安裝部(1100)係以將包含第1彎曲部(1331)之下側一部分之環支持部(1320)之下側一部分嵌埋於安裝部(1100)的方式，使用環支架(1300)作為嵌入件，藉由樹脂材料而射出成形。
