Mold and manufacturing method therefor |
摘要 |
Providing a mold and a manufacturing method therefor wherein protrusions are easy to be pressed into a resin base material and the protrusions are easy to be pulled out from the resin base material. The present invention provides a mold comprising a stamping surface (1a) formed depending on a via pattern and a protruding portion (21, 22) formed in convex shape from the stamping surface (1a), wherein the protruding portion has a base portion (111, 121) merging into a main surface of the stamping surface (1a) to have a curvature and a slope portion (113, 123) progressively decreasing in outer diameter thereof from the base portion (111, 121) to a top portion (112, 122) of the protruding portion (21, 22). |

1. A manufacturing method for a mold, comprising:
preparing a resin plate body cured; forming a hole in the resin plate body depending on a via pattern by irradiating laser or electron beam to a main surface of the resin plate body; laminating, after the forming step, a resist layer on the main surface of the resin plate body formed therein with the hole; removing, by a photolithographic method, the resist layer within a predetermined region including an opening region of the hole, depending on a wiring pattern; using a mold material to fill the hole formed in the resin plate body and to cover the main surface of the resin plate body: and removing the mold from the resist layer and resin plate body. |
