Abstract
A bar code forming method, which has the step of: forming the bar code which satisfies the following conditions, by transferring at least one portion of the transfer material onto the resin substrate by heating and pressing the transfer material onto the resin substrate, wherein, when the difference of the height between the concave portion formed on the resin substrate by the heating and pressing, and the convex portion protruding on the periphery of the concave portion, is h, and the distance between the top of the convex portion and the edge of the convex portion side of the concave portion, is d, and h is greater than or equal to 0.01 mm but less than or equal to 0.05 mm, and d is less than 0.1 mm.

A bar code forming method, comprising the steps of:
- heating and pressing a transfer material onto a resin substrate, thereby transferring at least one portion of the transfer material onto the resin substrate so that a bar code is formed, wherein the bar code satisfies the following conditions:
- 0.01 mm≦h≦0.05 mm, and d<0.1 mm
- wherein h represents a difference of a height between a concave portion formed on the resin substrate by heating and pressing, and a convex portion protruding on a periphery of the concave portion, and d represents a distance between a top of the convex portion and an edge of a convex portion side of the concave portion.
