The invention provides a light-source-hidden type helmet shell, a manufacturing method thereof and a light-source-hidden type helmet. The method includes: fixing a transparent base material piece, which comprises a preset light-permeable area and a shading area, at a to-be-processed position; providing a screen printing plate, and placing the screen printing plate corresponding to the light-permeable area; forming a color ink layer on the base material piece through the screen printing plate; taking down the screen printing plate, and covering the color ink layer with a light-permeable connecting ink layer to obtain a pre-formed product; placing the pre-formed product into a helmet shell mould, and using plastics sucking moulding to form the helmet shell. The light-source-hidden type helmet shell, the manufacturing method thereof and the light-source-hidden type helmet have the advantages that the shell is divided into the light-permeable area and the shading area, the light-permeable area is covered with the grid color ink layer, functions of light transmittance and shading are achieved, and the practicality of the light-source-hidden type helmet shell and the helmet is increased.
