The use under severe environmental conditions is increasing, and encapsulation with a single epoxy resin does not have sufficient weather resistance, and may cause damage or disconnection. Therefore, a transparent epoxy resin having a refractive index of 1.5
There has been proposed a sealing resin composition in which the above glass particles are blended to improve the weather resistance while maintaining the transparency (for example, JP-A-3-232370 and JP-A-6-322370).

る。In the present invention, the resin has a refractive index within a range of ± 0.0025 as compared with the refractive index of the resin and an Abbe number within a range of ± 5.0 as compared with the Abbe number of the resin. It is characterized by having a number. Here, the reason for setting the refractive index in the range of ± 0.0025 is to prevent the occurrence of anisotropy of the refractive index due to the filling of the glass filler and to prevent the transmittance from decreasing. The Abbe number is ±
The range of 5.0 was adjusted by adjusting the gradient of the refractive index of the glass particles to substantially match the gradient of the refractive index of the resin.
This is because the refractive index of the glass particles and the refractive index of the resin are the same not only on the sodium D line but also in a shorter wavelength range, and high transmittance is ensured in a wide wavelength range. And by such a configuration, it has sufficient weather resistance compared to plain resin, and in order to produce a resin composition excellent in transmittance in a wider wavelength range than when a conventional glass filler is added. It provides a novel glass filler for transparent resins.

Since the refractive index does not match at only one point of the sodium D line as in the conventional case, the refractive index also matches at a lower wavelength range. High transmittance can be secured.
