PROBLEM TO BE SOLVED: To provide a nonspherical resin particle connected body in which nonspherical resin particles having a specified shape providing sufficient strength and positional accuracy are connected with one another, and to provide a manufacturing method thereof. SOLUTION: The nonspherical resin particle connected body is provided in which, at least three nonspherical resin particles presenting a contour of such an approximately regular hexagonal shape that each particle projection image viewed from one direction has respective sides protruded outward are connected so as to be arranged side by side two-dimensionally in a plane vertical to the one direction, the nonspherical resin particle connected body is characterized in that, when the circumferential length of the nonspherical resin particle in the particle projection image relating to each nonspherical resin particle is (a), the major diameter is (b), each nonspherical resin particle satisfies a relational expression; 3/π≤äa/(b×π)}≤0.995 and the nonspherical resin particles are connected with one another so that the respective center positions of three nonspherical resin particles adjacent to one another are arranged on apex positions of a regular triangle in the above plane.
