PROBLEM TO BE SOLVED: To provide a bobbin for coils in which a plurality of the coils are arranged on a side face, a coil member using the bobbin, a magnetic-drive mechanism, a manufacturing method of the coil member, and a manufacturing method of the magnetic-drive mechanism. SOLUTION: A wire rod 61 is wound in order around winding support portions 44A, 44B, 44C and 44D of the bobbin 43 which is in a developed state, by which the coils C1, C2, C3 and C4 are formed. Each of connecting portions 42 is bent one by one, wherein the connecting portions connect between a sidewall portion 43a, a sidewall portion 43b, a sidewall portion 43c and a sidewall portion 43d, by which the bobbin 43 having a plurality of the coils on the side face is formed in three dimensions. In forming processes of the coils C1 to C4, as the wire rod 61 is wound on the bobbin 43 in the developed state from the same direction, manufacturing processes are also made easy.
