PROBLEM TO BE SOLVED: To provide an inflow cannula for blood circulation assisting devices, having a rigid structure, possessing a strong thrombus anchoring effect, thereby stably anchoring endothelial cells, and eliminating deformation or lowering of a dimension accuracy in a production process. SOLUTION: This inflow cannula has a porus structure in whole or in part, which is formed of filaments or porous moldings. Furthermore, the porous structure is formed of the one or more filaments crossed and/or contacted so that this or these filaments can form holes in the area surrounded by lines connecting adjacent crossing and/or contact points with each other on a surface of the porus structure.
