## Abstract

Provided are a low-cost and highly-precise structure-molding die that only requires a short production time, and a method of producing the die. The die is characterized by including: a plate-like first member 10 that serves as a base; a second member 2 that has cells 2 of a shape matching a to-be-molded structure and is joined to the first member 10; molding grooves 7 that have a predetermined depth and are disposed between the cells 2; and a supply hole 6 that communicates with the first member 10 at a predetermined intersection of the molding grooves 7 from an opposite side from the cells 2 joined.

## Claims

### Claim 1

A die, characterized by comprising:
a plate-like first member that serves as a base;
a second member that has cells of a shape matching a to-be-molded structure and is joined to the first member;
molding grooves that have a predetermined depth and are disposed between the cells; and
a supply hole that communicates with the first member at a predetermined intersection of the molding grooves from an opposite side from the cells joined.

### Claim 2

A die, characterized by comprising:
a first member that has a plate section and a first cell of a shape matching a to-be-molded structure;
a second member that has a second cell of a shape matching the to-be-molded structure and is joined to the first member;
molding grooves that have a predetermined depth and are disposed between the first cell and the second cell; and
a supply hole that communicates with the plate section of the first member at a predetermined intersection of the molding grooves from an opposite side from the first cell and the second cell joined.

### Claim 3

A die, characterized by comprising:
a first member that has a first plate section and a first cell of a shape matching a to-be-molded structure;
a second member that has a second plate section and a second cell of a shape matching the to-be-molded structure, and is joined with the second cell being inserted into the first member;
molding grooves that have a predetermined depth and are disposed between the first cell and the second cell; and
a supply hole that communicates with the first plate section of the first member and the second plate section of the second member at a predetermined intersection of the molding grooves from an opposite side from the first cell and the second cell.

### Claim 4

A method of producing a die, characterized by comprising:
a first step of processing a first member that serves as a base;
a second step of processing cells of a shape matching a structure that is to be molded at a second member;
a third step of joining the second member to the first member in such a way as to form molding grooves of a predetermined depth between the cells; and
a fourth step of making a supply hole communicate with the first member at a predetermined intersection of the molding grooves from an opposite side from the cells joined.

### Claim 5

A method of producing a die, characterized by comprising:
a first step of processing a first plate section of a first member and a first cell of a shape matching a to-be-molded structure;
a second step of processing a second plate section of a second member and a second cell of a shape matching the to-be-molded structure;
a third step of joining the second member to the first member in such a way as to form molding grooves of a predetermined depth between the first cell and the second cell; and
a fourth step of making a supply hole communicate with the plate section of the first member at a predetermined intersection of the molding grooves from an opposite side from the first cell and the second cell joined.

### Claim 6 (depends on 5)

The method of producing the die according to claim 5, characterized in that
the fourth step includes a step of cutting off the second plate section.

### Claim 7 (depends on 5)

The method of producing the die according to claim 5, characterized in that:
the second step includes a step of processing, in the second plate section, a first cell insertion hole into which the first cell is inserted; and
the third step includes a step of inserting the first cell into the first cell insertion hole.
