Provided is an organic light-emitting element having high light-emitting efficiency and a long element lifetime. Specifically, provided is an organic light-emitting element, including: an anode; a cathode; and an organic compound layer placed between the anode and the cathode, in which: the organic compound layer includes an emission layer; the emission layer includes at least a host and a guest; the guest is an iridium complex of a specific structure; the host is a heterocycle-containing compound; and a content of the host is 50 wt % or more with reference to a total amount of constituent materials for the emission layer.
