To provide a method for manufacturing a needle body for suppressing losses when processing a needle body having a fine structure and when performing transfer formation.

According to the method for manufacturing the needle body, a grinding blade provided with difference in level is used to obtain a needle body of multi-step structure in a simple process. Also, it is possible to produce a structure, in which only a contact area near a tip of the needle body likely causing the loss especially in a transfer formation is reduced, so that tip loss occurred by a plate and a molded product sticking to each other is reduced.
