VARIABLE-RESISTANCE ELEMENT AND METHOD FOR PRODUCING SAME

摘要

[Problem] To provide a low-cost variable-resistance element and a method for producing same. [Solution] The variable-resistance element (1) in one embodiment of the present invention is equipped with a bottom electrode layer (3), a top electrode layer (5), and an oxide semiconductor layer (4). The top electrode layer (5) is formed from a carbon material. The oxide semiconductor layer (4) has a first metal oxide layer (41) and a second metal oxide layer (42). The first metal oxide layer (41) is formed between the bottom electrode layer (3) and the top electrode layer (5), and has a first resistivity. The second metal oxide layer (42) is formed between the first metal oxide layer (41) and the top electrode layer (5), and has a second resistivity differing from the first resistivity.
