There is disclosed a method for fabricating a camera module includes the steps of: disposing a camera module body inside of a die; filling the die with a resin blocking a light; curing the resin; and removing the camera module body and the resin from the die. Here, disposing the camera module body inside of the die is disposing the camera module body having a lens holder secured on a sensor board inside of the die in such a manner that the side surface of the camera module body is not brought into contact with the side surface of the die. Filling the die with the resin is covering the upper end of the die with a lid so as to closely enclose the inside of the die, followed by filling the die with the resin. Taking the camera module body and the resin from the die is taking, from the die, the camera module body and the resin formed around the camera module body in close contact.

摘要:
Corrosion-resistive ceramic materials include a silicon based ceramic, wherein a percentage of respective metal elements other than metal elements constituting sintering agents and silicon is not more than 10 weight ppm. The corrosion-resistive ceramic materials show a high corrosion resistance with respect to corrosive substances and suppress particle generation due to an exposure to corrosive substances. Therefore, chippings and cracks do not occur easily during machining work.
