An intermediate coating composition used in forming an intermediate coating layer directly overlaid on a surface of an electrodeposition coating layer constructing a vehicle outer panel, the coating composition containing as resin components: (a) 1% to 27% by mass of a polycaprolactonetriol; (b) 20% to 60% by mass of a blocked isocyanate; and (c) 1% to 20% by mass of a melamine resin, each at a percentage content in entire resin components, and the coating composition further containing as a pigment component: (d) 1% to 10% by mass of talc in terms of pigment mass concentration. As the resin component, (e) greater than 0% to 10% by mass of an epoxy resin is preferably contained. A urethane curing catalyst is preferably contained in an amount of greater than 0.01 parts to 2 parts by mass with respect to 100 parts by mass of the entire resin components.
