A transparent film, the back-face of which has excellent resistance to scratch and printability, and a surface protection film which has such a transparent film are provided. A transparent filmhas a substrate layerformed of a transparent resin material, and a back-face layerwith a thickness of 1 &#x3bc;m or less provided on a first faceA thereof. A percent change in coefficient of friction &#x394;&#x3bc; is less than 10% for the transparent filmwhen the percent change is determined from a coefficient of friction &#x3bc;of the back-face layer after being conserved at 50&#xb0; C. and 15% RH for three days and a coefficient of friction &#x3bc;of the back-face layer after being conserved at 80&#xb0; C. and 80% RH for three days, with an absolute value of difference between the two coefficients of friction |&#x3bc;&#x2212;&#x3bc;| being divided by the smaller value of the two coefficients of friction.

Transparent film and use thereof

The present invention relates to a transparent conductive film which is excellent in dotting property under a heavy load and excellent in bending resistance. Provided is a transparent conductive film, comprising a flexible transparent base; and a transparent conductive layer formed on the flexible transparent base and including a crystalline indium/tin composite oxide, wherein a compressive residual stress of the transparent conductive layer is 0.4 to 2 GPa.
