The present invention relates to a package structure of an optical module. The light emitting chip and the light receiving chip are disposed on the light emitting region and the light receiving region of the substrate, respectively. Two encapsulating gels are coated on the light emitting chip and the light receiving chip to form a first and a second hemispherical lens portions thereon, respectively. A cover is affixed on the substrate and each of the encapsulating gels and has a light emitting hole and a light receiving hole, where the first and second lens portions are accommodated, respectively. In this way, the package structure of an optical module of the present invention can be made with the encapsulating gels of different curvatures according to different needs to improve the luminous efficiency of the light emitting chip effectively and to improve the reception efficiency of the light receiving chip.
