摘要

A nickel thin film is formed, for example, to a thickness of 2 nm or more on a polyethylene naphthalate substrate by a vacuum evaporation method. A magnetoresistance effect element using ferromagnetic nano-junction is comprised by using two laminates each comprising a nickel thin film formed on a polyethylene naphthalate substrate, and joining these two laminates so that the nickel thin films cross to each other in such a manner that edges of the nickel thin films face each other.
