Summary:PROBLEM TO BE SOLVED: To provide an optical module in which the Bragg reflection wavelength of the fiber grating in the optical fiber can be maintained at the set wavelength for a long time. SOLUTION: The optical fiber 2 having the fiber grating formed is inserted into a package 1 and the optical fiber 2 is fixed to the package 1 with an adhesive 8 at the fixing parts 13, 14 on both sides of the part 6 where the fiber grating is formed. The adhesive 8 contains an inorganic filler which improves the moisture resistance, by >=20 wt.% and <=60 wt.%, for example.
