The present invention relates to a compound represented by the formula
wherein ring A is a nitrogen-containing heterocycle;
ring B is an aromatic ring optionally having substituent(s);
ring D is an aromatic ring optionally having substituent(s);
L is a group represented by the formula
R2, R3, R4a and R4b are each independently a hydrogen atom, an optionally halogenated C1-6 alkyl group or an optionally halogenated C3-6 cycloalkyl group, or R2 and R3 are optionally bonded via an alkylene chain or an alkenylene chain, or R4a and R4b are optionally bonded via an alkylene chain or an alkenylene chain;
R1 is a hydrogen atom or a substituent;
m and n are each independently an integer of 0 to 5;
m+n is an integer of 2 to 5; and
is a single bond or double bond, or a salt thereof; and the like.
