(57) [Problem] To provide a plastic optical waveguide material which is excellent in electric characteristics, heat resistance, and transparency, can be manufactured at low cost, and can realize a large area. A material for a plastic optical waveguide for optical communication, comprising a polybenzoxazole resin having a structure in which a polybenzoxazole precursor having a repeating unit represented by the general formula (1) is closed. Embedded image (In the formula (1), n represents an integer from 1 to 1000; And Y represent a divalent organic group, at least one of which contains fluorine. ) |
