  Chirality is one of the important assymmetrical property in wide area of
natural science, which has been studied to predict molecular behavior. One of
good methods to analyze molecules with complex structures is representing them
as graphs embedded in 3-dimensional space. So it is important to study the
chirality of spatial graphs to understand structure of chiral molecules.
Moreover, Robertson and Seymour's graph minor theorem implies that a set of
minor minimal graphs with respect to intrinsic properties is finite. So it is
also important to find a complete set of minor minimal graphs for intrinsic
properties. In this paper, we classify minor minimal intrinsically chiral
graphs among simple graphs of size up to twelve.
