    摘要： The surface of a blank for a textured amorphous carbon substrate is polished in a surface with a predetermined surface roughness, and then the blank with a polished surface is heated at a predetermined temperature in an oxidizing atmosphere to form minute irregularities in the polished surface through a reaction expressed by C+O.sub.2 =CO.sub.2 so that the surface is textured in an appropriate surface roughness. A randomly textured amorphous carbon substrate has a randomly textured surface with a surface roughness Ra in the range of 20 to 100 .ANG. and the ratio Ra.sub.2 /Ra.sub.1, where Ra.sub.1 is the surface roughness with respect to a circumferential direction, and Ra.sub.2 is the surface roughness with respect to a radial direction, in the range of 0.75 to 1.25 .ANG.. A concentrically textured amorphous carbon substrate has a concentrically textured surface with a surface roughness Ra in the range of 30 to 100 .ANG. or in the range of 40 to 200 .ANG., and the ratio Ra.sub.2 /Ra.sub.1 of 1.75 or greater.

    摘要： In an optical fiber array (1) which has a V-groove substrate (2) formed in its surface (2a) with V-grooves (3) for arranging optical fibers, a plurality of optical fiber cores (61) fixedly bonded in each individual V-groove (3) of the V-groove substrate (2), and a pressure plate (4) fixedly bonded to surfaces of the optical fiber cores (61), an adhesive comprising a resin composition (component A) having an OH group after curing and a filler (component B) is used to fixedly bond the V-groove substrate (2), the optical fiber cores (61), and the pressure plate (4). This adhesive has a glass transition temperature that is somewhat lower than the ambient test temperature and possesses somewhat higher elasticity. Therefore, large internal stress does not occur in the adhesive even under conditions of high temperature and high humidity. Consequently, no peeling occurs as a result of moisture penetration since gaps cannot form between the pressure plate (4) and the adhesive.
