Electrode for electrical discharge machining and method for manufacturing honeycomb structure forming die

摘要

An electrode for electrical discharge machining which makes it possible to form slits of a honeycomb structure forming die so that a slit width on a front surface side is smaller than a slit width on a back hole side is provided. The electrode for electrical discharge machining includes: plural plate-shaped discharge portions with a thickness that is gradually increased toward tips thereof; and a plate-shaped support portion to which end portions of the plural discharge portions on a side opposite to the tips are connected, wherein a difference between a thickness of the tip; and a thickness of the end portion on the side opposite to the tip ranges from 5 μm to 500 μm in the discharge portion.
