Summary:A coil module includes a coil conductor including a plurality of coil elements and a plurality of wire electrodes disposed on a circuit board, each of the plurality of coil elements including a pair of leg portions and a bridge portion connecting one end portions of the pair of leg portions together, the plurality of coil elements being disposed to cross a winding axis. A method for manufacturing the coil module includes an assembly forming step of integrating the plurality of coil elements with resin to form a coil element assembly, and a conductor forming step of mounting the coil element assembly on the circuit board to complete the coil conductor wound about the winding axis. In the conductor forming step, the resin is introduced into a die set in which the plurality of coil elements are arranged to form a block, to thus form the coil element assembly.
