The invention relates to a light-transmitting structure for automotive interior lighting and a preparation method thereof. The light-transmitting structure comprises a light-transmitting elastic layer, a first connecting layer, a light-transmitting pattern layer, a second connecting layer and an injection molding part which are sequentially stacked. The preparation method comprises the steps thatthe light-transmitting elastic layer, the light-transmitting pattern layer and the injection molding part are sequentially attached through a hot melt adhesive, a first connecting layer and a second connecting layer are formed between the light-transmitting elastic layer and the light-transmitting pattern layer and between the light-transmitting pattern layer and the injection molding part respectively, and the light-transmitting structure is formed. Compared with the prior art, the light-transmitting structure has the advantages of being simple in structure, easy to manufacture, low in cost and the like.
