The exotic hadrons, those, which have content beyond the conventional scheme of mesons, consisting of a quark and an antiquark, and baryons, consisting of three quarks, were predicted with the quark model itself. However first observation of an exotic candidate was made only less than 15 years ago. Since then quite a number of exotic-like states was discovered and some of them were proved to consist of more than three quarks. Various theoretical approaches predict different masses and quantum numbers of such states. Thus search for the new exotic hadrons and study of their properties is important for better understanding of their internal structure. The talk will cover the latest results on the topic from the LHCb experiment.
