摘要： Fibers for fiber-reinforced resin of the present invention are fibers for fiber-reinforced resin to which a sizing agent is adhered. The fibers are at least one selected from carbon fibers and glass fibers, and an ester bond (—COO—) generated by denaturation of the sizing agent is present on surfaces of the fibers. A method for producing the same according to the present invention includes: subjecting fibers to which a sizing agent is adhered to at least one treatment selected from the group consisting of ozone oxidation, ultraviolet irradiation at a wavelength of 400 nm or less, and a plasma treatment. The fibers are at least one selected from carbon fibers and glass fibers. Thus, it is possible to provide carbon fibers having enhanced wettability to a matrix resin and thereby allowing the matrix resin to be impregnated between the fibers easily.

摘要： The present invention provides a package method of a substrate. By forming a plurality of support parts which are separately located at the border position of the package cover plate, the gap of the package cover plate and the substrate is limited after para bonding the package cover plate and the substrate. Thus, the seal height of the seal which does not contain the spacers can be ensured, and under circumstance of certain seal coating volume, the seal width of the seal also can be ensured. Furthermore, by cutting off the plurality of support parts, and border parts of the substrate and the package cover plate contacting with the support parts, the substrate packaged with the seal which does not contain the spacers can be obtained, and it is ensured that the seal has the consistent height and width.
