The light emitting element 510 is fixed on the circuit board 530, the light transmitting member 520 is located on a side of the circuit board 530 facing away from the first camera module 400, and the light transmitting member 520 corresponds to the light emitting element 510, so that light emitted by the light emitting element 510 can be transmitted to the outside of the mobile terminal 10 through the light transmitting member 520. The section of the light-transmitting member 520 is a T-shaped structure, and the light transmittance is not less than 50%. The top frame 111 is provided with a first through hole 601, and part of the structure of the light-transmitting member 520 penetrates through the first through hole 601 and is fixed to the top frame 111.
