A coil device includes a conductor and a terminal electrode. The conductor is embedded in a core body and wound in a coil shape. The terminal electrode is formed on an end surface of the core body and connected with a lead end of the conductor. The coil device further includes a dummy conductor embedded in the core body separately from the conductor. An end part of the dummy conductor exposed from the end surface of the core body separately from the lead end is connected with the terminal electrode.
