A hollow cylindrical filter formed by winding a metal wire rod in a spiral and multilayered manner, wherein the hollow cylindrical filter is configured to perform filtering by allowing a fluid to pass therethrough from an inner diameter side to an outer diameter side, or from the outer diameter side to the inner diameter side, the metal wire rods that configure wire rod layers have an irregular shape in cross section throughout the entire length in a longitudinal direction of the metal wire rods , wherein the irregular shape is defined by at least one recess formed on at least one of a first surface and a second surface of the metal wire rods , wherein the recess is formed along the longitudinal direction of the metal wire rods , the metal wire rods are wound so that the first surface faces the inner diameter side and the second surface faces the outer diameter side or so that the first surface faces the outer diameter side and the second surface faces the inner diameter side, and extend in a direction inclined with respect to an axial direction of the hollow cylindrical filter, the metal wire rods that configure the adjacent wire rod layers extend in directions intersecting with each other with a fixed inclined angle with respect to an axial direction, to form a plurality of communication paths communicating in a direction into which the wire rod layers overlap with each other, and an intersection portion space that allows the plurality of communication paths to communicate with each other is formed by the at least one recess formed in the metal wire rod that configures at least one of the wire rod layers, at the intersection between the metal wire rod that configures one wire rod layer and the metal wire rod that configures an adjacent wire rod layer to the one wire rod layer. the hollow cylindrical filter is configured to perform filtering by allowing a fluid to pass therethrough from an inner diameter side to an outer diameter side, or from the outer diameter side to the inner diameter side, the metal wire rods that configure wire rod layers have an irregular shape in cross section throughout the entire length in a longitudinal direction of the metal wire rods , wherein the irregular shape is defined by at least one recess formed on at least one of a first surface and a second surface of the metal wire rods , wherein the recess is formed along the longitudinal direction of the metal wire rods , the metal wire rods are wound so that the first surface faces the inner diameter side and the second surface faces the outer diameter side or so that the first surface faces the outer diameter side and the second surface faces the inner diameter side, and extend in a direction inclined with respect to an axial direction of the hollow cylindrical filter, the metal wire rods that configure the adjacent wire rod layers extend in directions intersecting with each other with a fixed inclined angle with respect to an axial direction, to form a plurality of communication paths communicating in a direction into which the wire rod layers overlap with each other, and an intersection portion space that allows the plurality of communication paths to communicate with each other is formed by the at least one recess formed in the metal wire rod that configures at least one of the wire rod layers, at the intersection between the metal wire rod that configures one wire rod layer and the metal wire rod that configures an adjacent wire rod layer to the one wire rod layer. <EOS>
