<p>A resin-coated metallic material comprising a metallic base, at least one surface of which has been coated with a resinous coating film containing thermally conductive particles. When a photograph of a planar-direction section of the resinous coating film taken with a scanning electron microscope is subjected to image analysis, the thermally conductive particles observed in the field of view satisfy the following requirements (1) to (3). (1) The thermally conductive particles have an aspect ratio, which is the value obtained by dividing the maximum length by the minimum length of the particles (maximum length/minimum length), of 3.0 or higher on average, (2) when the thermally conductive particles are examined for the angle of inclination of the longest axis with the planar-direction horizontal line, the frequency of thermally conductive particles having an angle of inclination of 0º or larger but less than 30º is 40% or higher, and (3) the areal proportion of the thermally conductive particles is 30% or higher.</p> |
