The utility model provides a frame component, its pollution that can prevent component on every side. Frame component is used for utilizing the sealing layer that is formed by sealing material to seal light semiconductor component's frame component. Frame component includes: the 1st frame portion, its mode in order to form the 1st space constitutes, the 2nd frame portion, it separates the interval with the outside in the 1st frame portion and the 1st frame portion and form the mode configuration in the 2nd space between its and the 1st frame portion to with the mode configuration of surrounding the 1st frame portion, binding portion, its be used for with the 1st frame portion with the 2nd frame portion links up. The 1st space supplies sealing layer and the configuration of light semiconductor component. The remaining part outside the part of smooth semiconductor component's sealing layer has been sealed in formation that the 2nd space is arranged in accomodating sealing material.
