The present invention provides an electromagnetic wave-permeable brilliant coated resin product which has a brilliant coating film formed by applying a coating composition that includes a planar brightening material formed from aluminum, on a resin substrate. Within the brilliant coating film, the brightening material is oriented in a state such that a plane thereof is biased toward a direction that follows a surface of the brilliant coating film, and an average overlapping quantity (y), which is an average of a quantity of brightening material that crosses one orthogonal line that is orthogonal to the surface of the brilliant coating film, and an average inter-brightening material distance (x), which is an average of distances on the orthogonal line between adjacent brightening materials that cross said orthogonal line, satisfy the following two formulae:y&#x2267;0.5 &#x2003;&#x2003;(formula 1), and&#x2266;0.3969+0.594 &#x2003;&#x2003;(formula 2),
