in Formula (SQ2), a ring Z 3 and a ring Z 4 each independently represent a polycyclic aromatic ring having a 5-membered or 6-membered nitrogen-containing heterocyclic ring, which may have one or a plurality of substituents,
a ring Z 5 and a ring Z 6 each independently represent a 4-membered to 9-membered hydrocarbon ring or heterocyclic ring, which may have one or a plurality of substituents,
in a case where the ring Z 3 to the ring Z 6 have a plurality of substituents, the plurality of substituents may be the same or different from each other,
Rs 5 to Rs 8 each independently represent a hydrogen atom or a substituent,
Ar 1 represents a group represented by any one of Formulae (Ar-1) to (Ar-4), and
n1 represents an integer of 1 or 2,

in the formulae, Xa 1 to Xa 8 each independently represent a sulfur atom, an oxygen atom, or NRx a , in which Rx a represents a hydrogen atom or a substituent, and * represents a bonding hand.

2. The near-infrared absorbing photosensitive composition according to claim 1 , further comprising:
a resin.

3. The near-infrared absorbing photosensitive composition according to claim 2 ,
wherein the resin includes a resin having an acid group.

4. The near-infrared absorbing photosensitive composition according to claim 3 ,
wherein the near-infrared absorbing photosensitive composition includes 10 to 1000 parts by mass of the resin having an acid group with respect to 100 parts by mass of the polymerizable compound.

5. The near-infrared absorbing photosensitive composition according to claim 1 , further comprising:
a pigment derivative.

6. A cured film obtained from the near-infrared absorbing photosensitive composition according to claim 1 .

7. An optical filter comprising:
the cured film according to claim 6 .

8. The optical filter according to claim 7 ,
wherein the optical filter is a near-infrared cut filter or a near-infrared transmitting filter.

9. A method for forming a pattern, comprising:
forming a composition layer on a support using the near-infrared absorbing photosensitive composition according to claim 1 ;
patternwise exposing the composition layer; and
removing an unexposed area of the composition layer by development.

10. A laminate comprising:
the cured film according to claim 6 ; and
a color filter including a chromatic colorant.

11. A solid-state imaging element comprising:
the cured film according to claim 6 .

12. An image display device comprising:
the cured film according to claim 6 .

13. An infrared sensor comprising:
the cured film according to claim 6 .

14. A near-infrared absorbing photosensitive composition comprising:
a compound represented by Formula (SQ3);
a polymerizable compound;
a photopolymerization initiator; and
a solvent,

in Formula (SQ3), a ring Z 7 and a ring Z 8 each independently represent a polycyclic aromatic ring having a 5-membered or 6-membered nitrogen-containing heterocyclic ring, which may have one or a plurality of substituents,
a ring Z 9 and a ring Z 10 each independently represent a 4-membered to 9-membered nitrogen-containing heterocyclic ring, which may have one or a plurality of substituents,
in a case where the ring Z 7 to the ring Z 10 have a plurality of substituents, the plurality of substituents may be the same or different from each other,
Ar 2 represents a group represented by any one of Formulae (Ar-1) to (Ar-4), and
n2 represents an integer of 0 to 2,
