A coil unit configured to be used in contactless transmission of electric power for running a vehicle includes a coil, and a plate-shaped coil holder that holds the coil. The coil holder has a spiral-shaped first passage and a spiral-shaped second passage. The first passage is formed along a plate surface of the coil holder, and a conductor constituting the coil is disposed in the first passage.
