The present invention provides a non-human animal model of myocardial infarction, which can be created by a less invasive method, shows an extremely low mortality during and after surgical induction of myocardial infarction, ensures the blood reflow after necrosis of cardiac muscles caused by blocking blood flow, and therefore, is usable in topical therapy for myocardial infarction and studies on regenerative medicine, and a method for creating the non-human animal model. The creation method comprises: a step of administering a temporary embolic agent to a branch blood vessel of a heart coronary artery to block blood flow in the branch blood vessel and a step of, after a definite period of time after said vascular branch blockage, administering a temporary embolic agent to the target coronary artery which is intended to induce myocardial infarction to block blood flow in the target coronary artery. Preferred is the branch blood vessel is a branch of the target coronary artery in which myocardial infarction is to be induced.
