- La is a direct linkage, a substituted or unsubstituted arylene group of 6 to 30 ring-forming carbon atoms, or a substituted or unsubstituted heteroarylene group of 2 to 30 ring-forming carbon atoms,
- C1 and C2 are each independently a substituted or unsubstituted adamantyl group, a substituted or unsubstituted cyclohexyl group, a substituted or unsubstituted bicycloheptanyl group, a substituted or unsubstituted bicyclooctanyl group, or a substituted or unsubstituted triphenylsilyl group,
- a case where both C1 and C2 are substituted or unsubstituted adamantyl groups is excluded, and
- M is represented by any one selected from among the following Formula 1-a to Formula 1-c:

- Ra to Rl, R3, and R4 are each independently a hydrogen atom, a deuterium atom, a halogen atom, a substituted or unsubstituted alkyl group of 1 to 20 carbon atoms, a substituted or unsubstituted aryl group of 6 to 30 ring-forming carbon atoms, or a substituted or unsubstituted heteroaryl group of 2 to 30 ring-forming carbon atoms, or combined with an adjacent group to form a ring,
- in Formula 1-b, any one selected from among Rc to Rl is a part connected with Formula 1,
- in Formula 1-a and Formula 1-c,
- is a part connected with Formula 1,
- in a case where M in Formula 1 is represented by Formula 1-b or Formula 1-c, at least one selected from among C1 and C2 in Formula 1 is a bicycloheptanyl group,
- n1 is an integer of 0 to 4,
