The present invention provides a fused heterocyclic compound having a tyrosine kinase inhibitory action, which is represented by the formula:
wherein
ring A is an optionally substituted benzene ring;
ring B is an optionally substituted benzoisothiazole ring;
R
1
is a hydrogen atom, a halogen atom, or an optionally substituted group bonded via a carbon atom, a nitrogen atom or an oxygen atom;
R
2
is a hydrogen atom, or an optionally substituted group bonded via a carbon atom or a sulfur atom;
R
3
is a hydrogen atom or an optionally substituted aliphatic hydrocarbon group;
or
R
1
and R
2
, or R
2
and R
3
are optionally bonded to each other to form an optionally substituted ring structure;
or
R
3
is optionally bonded to the carbon atom on ring A to form an optionally substituted ring structure;
or a salt thereof.
