Provided are a tire mold molding element, etc. that can increase the degree of freedom with which a coating layer is arranged on a ground-contact element of a tire and that can more stably arrange the coating layer in a prescribed position. The present invention is a tire mold molding element (1) that is for vulcanization molding a tire tread (2) and that has: a molding surface (3) that is for molding a plurality of ground-contact elements (4) of the tread, which comprise a ground-contact surface (43) that will contact a road surface and a lateral-direction side surface (44) and a circumferential-direction side surface (45) that are connected to the ground-contact surface; and thin plates (5) that are provided with a main body (51) and that are provided so as to cut a coating layer (10) that is pre-arranged upon an un-vulcanized raw tire (9). At least one of the thin plates has a protruding part (6) that protrudes from the main body in the thickness direction of the thin plate so as to cover at least one part of the lateral-direction side surface of a ground-contact element and that guides the cut coating layer in the depth direction of the raw tire. At least two adjacent thin plates each have: an expanded-width part (8) that is provided at an end part (81) that is on the opposite side from the molding surface; and a cutting means (7) that protrudes from the expanded-width part toward the side opposite the molding surface.
