A control device that controls a manufacturing line including: a mounter configured to place at least one electronic component of a designated type at a designated position; a resin shaping machine (104, 105) configured to shape into a shaped resin body in which the at least one electronic component disposed at the designated position is embedded; and a printing machine configured to form a wiring on a surface of the shaped resin body by ejecting conductive ink according to a designated pattern, the control device comprising: a specification setting unit configured to set a specification of a product to be manufactured through the manufacturing line and a planned number of products; a mounting program selector configured to select a mounting program to be used by the mounter from a plurality of mounting programs indicating the type and the position of the at least one electronic component; a first counter configured to count a mounting number from the mounter using the mounting program, for each of the mounting programs selected by the mounting program selector; a second counter configured to count a defective product number of the shaped resin body in which the at least one electronic component disposed using the mounting program is embedded for each of the mounting programs; a printing program selector configured to select a printing program to be used by the printing machine from a plurality of printing programs indicating the pattern; and a third counter configured to count a printing number from the printing machine using the printing program, for each of the printing programs selected by the printing program selector, wherein when the specification setting unit sets a first specification and a first planned number of products, and then sets a second specification and a second planned number of products, the mounting program selector is configured to select a first mounting program corresponding to the first specification, and then select a second mounting program corresponding to the second specification according to matching between the mounting number corresponding to the first mounting program and the first planned number of products, the printing program selector is configured to select a first printing program corresponding to the first specification, and then select a second printing program corresponding to the second specification according to matching between (i) a sum of the printing number corresponding to the first printing program and the defective product number corresponding to the first mounting program and (ii) the first planned number of products, the plurality of mounting programs include at least two mounting programs corresponding to a third specification, and when the specification setting unit sets the third specification and a third planned number of products, the mounting program selector is configured to arbitrarily select one mounting program from the at least two mounting programs. a specification setting unit configured to set a specification of a product to be manufactured through the manufacturing line and a planned number of products;
