MANUFACTURING METHOD OF MICRO HOLLOW PROJECTION TOOL, AND MICRO HOLLOW PROJECTION TOOL

摘要

To provide a manufacturing method of a micro hollow projection tool, capable of manufacturing a micro hollow projection tool having a sheet part formed from a first material, and a micro hollow projection formed with a skeleton for maintaining a solid form of the micro hollow projection from the first material or a second material.SOLUTION: A manufacturing method of a micro hollow projection tool including a sheet part 2 and a micro hollow projection 3 includes: a step of partially arranging a second material 3a on a base material sheet 20 formed from a first material, and obtaining an intermediate sheet 23 in which an other material laminated part 26 laminated with the base material sheet 20 and the second material 3a is partially formed; and a projection formation step of forming the micro hollow projection 3 by piercing a projection die 410 having heating means into the other material laminated part 26. The first material and the second material are skeleton formation materials containing thermoplastic resin, and a skeleton for maintaining a solid form of the micro hollow projection is formed by the skeleton formation materials.SELECTED DRAWING: Figure 7
