• wherein the film portion includes
• an organic resin phase containing one or more of a urethane group, an epoxy group, and an ester group;
• an organic compound phase formed of an organic silicon compound;
• and
• optionally an inorganic compound phase formed of an inorganic silicon compound,
• a total volume percentage of the organic compound phase and the inorganic compound phase to a total volume of the film portion is 16 vol % to 84 vol %,
• a volume percentage of the organic compound phase to the total volume of the film portion is 16 vol % to 84 vol %,
• a volume percentage of the inorganic compound phase to the total volume of the film portion is limited to 10 vol % or less,
• the organic silicon compound includes
• a Si—C bond;
