This method for joining cycloolefin polymers (COP) is for joining a first material 81 that is a COP to a second material 82 that is, for example, a COP or glass, the method including: a step of exposing at least the joining surface of the first material 81 to H 2 O plasma; and a step of joining the joining surface of the first material 81 to the joining surface of the second material. According to this method, it is possible to join a cycloolefin polymer (COP) to a partner material without applying high pressure or a high temperature and without altering optical characteristics. |
