A mold for manufacturing a wiring circuit component, comprising: a first fixed mold and a second fixed mold on a fixed side, and a movable mold on a movable side, wherein the movable mold has protrusible and retractable opposite-surface projections provided on a surface thereof opposing the first fixed mold or the second fixed mold; the first fixed mold has a one-surface projection and communication pins provided on a surface thereof opposing the movable mold, while the second fixed mold has a planar site provided on a surface thereof opposing the movable mold; the first fixed mold is equipped with a first resin supply portion which, when the first fixed mold and the movable mold are mold-clamped, with the opposite-surface projections of the movable mold protruding, is arranged to supply a non- conductive resin to a space part to shape a board section having a one-surface groove at a site of the one-surface projection, communication parts at sites of the communication pins, and opposite-surface grooves at sites of the opposite-surface projections; and the second fixed mold is equipped with a second resin supply portion which, when the second fixed mold and the movable mold are mold-clamped, with the opposite-surface projections of the movable mold being retracted, while the shaped board section is mounted on the movable mold, is arranged to supply a conduction-side resin, which will become conductive, to the one-surface groove, the opposite-surface grooves, and the communication parts of the board section to shape a wiring portion, characterized in that a plurality of types of the opposite-surface projections are provided, and fixed to a common plate; the plate is supported reciprocatably by the movable mold; the plate being arranged to reciprocatingly move to enable the opposite- surface projections to be protruded and retracted at the surface opposing the second fixed mold; the movable mold is equipped with tilt members for reciprocating the plate; the tilt members are arranged to tilt to one side to move the plate so as to protrude the opposite-surface projections, and to tilt to an opposite side to move the plate so as to retract the opposite-surface projections; the first fixed mold is equipped with first push pins for tilting the tilt members to the one side for positional regulation when mold-clamped in cooperation with the movable mold; and the second fixed mold is equipped with second push pins for tilting the tilt members to the opposite side via the plate for positional regulation when mold-clamped in cooperation with the movable mold. a first fixed mold and a second fixed mold on a fixed side, and a movable mold on a movable side, wherein the movable mold has protrusible and retractable opposite-surface projections provided on a surface thereof opposing the first fixed mold or the second fixed mold;
