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 1 with a thickness that is gradually increased toward tips thereof; and a plate-shaped support portion 2 to which end portions 5 of the plural discharge portions 1 on a side opposite to the tips 4 are connected, wherein a difference between a thickness of the tip 4; and a thickness of the end portion 5 on the side opposite to the tip 4 ranges from 5 µm to 500 µm in the discharge portion 1.
