Abstract

This invention provides an encapsulated electronic component, a method of making the same and an encapsulating material, the encapsulating material comprising a resin containing 40 to 70% by volume of glass balls preferably having a mean diameter of less than 1mm. The resin is preferably a polyurethane resin.
