In terms of structure, (1) the cost of plastic materials is low (2) the heat treatment temperature during plastic molding is low, resulting in low energy costs (3) if a synthetic resin adhesive is used during sealing, it is possible to bond and harden at room temperature. Therefore, the energy cost is low +41 When this structure is used to encapsulate a color image sensor using an organic (gelatin, etc.) color filter, there is no high temperature treatment, so the optical characteristics of the color filter will not deteriorate due to heat. does not occur at all.
