Can be integrally connected, and the temple 1 of the first embodiment according to the present invention can be configured.

In the temple manufacturing method according to this embodiment having the above-described structure, the hole 6 is formed in the center of the modern 6 by the temporary core material 14, and after the modern 6 is completely cooled and hardened. Since the main core material 15 is inserted into the hole 9 of the modern 6, the main core material 15 is not discolored or deformed under the influence of the heat of the modern 6. Therefore, the modern 6 can be made of transparent or translucent resin, and the main core material 15 having the metal surface coated can be used, so that the range of design can be widened.

Further, the temporary core 14 is inserted into the center of the modern 6 while the interior of the modern 6 is still soft, and the temporary core 14 is pulled out to form the hole 9 after the modern 6 is cooled and hardened. Since it was done, surely a hole 9 in the center of the modern 6
Can be formed. Therefore, when the main core material 15 is inserted into the hole 9, the main core material 15 does not deviate from the center of the modern 6, and the main core material 15 deviates from the center and the appearance is bad. There is no such thing.

Further, the temple body 2 is integrally molded at one end of the modern 6 in the longitudinal direction, and the molding material for molding the temple body 2 in the support hole 9 provided in the temple body mounting portion 7 of the modern 6 is formed. Since a part of it goes around, the modern 6 and the temple body 2 can be completely integrated. Therefore, a gap is not formed between the two, and the modern 6 does not drop off from the temple body 2, so that the function as the temple 1 can be maintained for a long time.

Further, the modern body 6 is formed of a transparent body or a semi-transparent body, and the temple body mounting portion 7 (locked portion 8) of the modern body 6 is made transparent, whereby the temple body mounting portion 7 is designed as the temple 1. Since it can be a part of, the width of the design can be widened also by this.

In the method of manufacturing the temple, the method of manufacturing the temple 1 of the first embodiment has been described, but the method of manufacturing the temple 1 of the second, third and fourth embodiments is described. Needless to say, it may be applied to manufacturing, and in that case, the same effect can be obtained.
