A successive deposition apparatus by which a reduction in the luminous efficiency of a light-emitting element can be suppressed even in high-speed deposition of a light-emitting layer thereof is provided. The apparatus includes: a second deposition chamber; a third deposition chamber coupled to the second deposition chamber; a transfer unit for transferring a substrate from second deposition chamber to third deposition chamber; plural third deposition sources arranged in the substrate transfer direction in the second deposition chamber; and a fourth and fifth deposition sources alternately arranged in the transfer direction in the third deposition chamber. In the third deposition chamber, the fourth deposition source is placed nearest to the second deposition source. The fourth deposition source contains a host material, and the fifth deposition source contains a dopant material. The HOMO level of a material of the third deposition source is adjusted to that of the host material.
