Abstract
In a die which has a regular polyhedron form and which can be opened into a continuous polygonal form on a plane, boundary areas (Rb) between planes ( through ) on the inner side of the regular polyhedron have inclination angles determined according to the regular polyhedron. In addition, engaging portions ( ) not exceeding the respective boundary areas (Rb) are placed on the boundary areas (Rb) of predetermined planes ( through ). Such a die is formed by injecting plastic resin within a mold ( ) according to the form of the opened die. This realizes a three-dimensional die capable of being opened onto a two-dimensional plane, which has only been fictionally conceived, and further provides a manufacturing method thereof.
