    摘要: A camera module is composed from a lens unit including at least one lens, a barrel provided with the lens and having a barrel opening, and a lens holder for holding the barrel; and an image pickup device portion provided under the lens unit and having an image pickup device housing space in which an image pickup device is hermetically provided. The barrel opening of the barrel has an annular edge which serves as a diaphragm, and the annular edge of the barrel opening has a lower annular corner portion which is located on the side of the lens, wherein the lower annular corner portion of the annular edge is formed so as to have a rounded cross-sectional shape and staining is formed on the lower annular corner portion.
