PROBLEM TO BE SOLVED: To prevent an adhesive 11 from entering a sealed space formed as a CCD 6 and a glass chip 9 comes into contact with each other with a spacer 10 interposed.SOLUTION: In an atmospheric pressure controlled chamber in which the atmospheric pressure can be lowered, a glass chip 9 coated with an adhesive 11 is put close to a spacer 10 to bond the glass chip 9 and CCD 6 together. The CCD 6 and glass chip 9 are held one over the other and a sealed space 40 is formed which has its periphery surrounded with the spacer 10 and adhesive 11. The atmospheric pressure is lower outside the sealed space 40 than inside the sealed space 40, so an adhesive 11 having entered the sealed space 40 is pushed out of the sealed space 40. |
