    Abstract: The invention is directed to a process for producing polyimide film, including stretching, at 150° C. to 380° C. and a stretch ratio of 1.2 to 4.0, an unstretched polyimide film which is formed from a polyimide having a repeating unit represented by formula (1): (wherein R represents a tetravalent group derived from cyclohexane; and Φ represents a divalent aliphatic, alicyclic, or aromatic group, or a combination thereof that has a total number of carbon atoms of 2 to 39 and may have at least one connecting group selected from the group consisting of —O—, —SO2—, —CO—, —CH2—, —C(CH3)2—, —OSi(CH3)2—, —C2H4O—, and —S—) and which has an organic solvent content of 0.5 wt. % or more and less than 30 wt. %. The produced polyimide film exhibits transparency, excellent heat resistance, and reduced dimensional changes.

    Abstract: An optical waveguide, an optical printed circuit board equipped with the optical waveguide, and methods of manufacturing the optical waveguide and the optical printed circuit board are disclosed. The optical waveguide can include: a first cladding layer; a core formed on the first cladding layer; an alignment pattern, having a predefined positional relationship to the core, formed on the first cladding layer; a target mark formed on the alignment pattern to indicate a position of the alignment pattern; and a second cladding layer formed on the first cladding layer to cover the core, the alignment pattern, and the target mark. In such an optical waveguide, circuit patterns, etc., formed over the second cladding layer may be precisely and efficiently aligned with the core.
