A light-mixing multichip package structure includes a substrate unit, a light-emitting unit, a frame unit, and a package unit. The light-emitting unit includes at least one first light-emitting module with red light-emitting chips and at least one second light-emitting module with blue light-emitting chips. The frame unit includes at least one first continuous colloid frame and at least one second continuous colloid frame respectively surrounding the first light-emitting module and the second light-emitting module. The package unit includes a transparent colloid body and a phosphor colloid body respectively covering the first light-emitting module and the second light-emitting module. Hence, when the red light source generated by matching the red light-emitting chips and the transparent colloid body and the white light source generated by matching the blue light-emitting chips and the phosphor colloid body are mixed with each other, the CRI of the light-mixing multichip package structure can be increased.
