摘要：
A variable resistance element includes a first conductive portion; an insulating film pattern provided on the first conductive portion; a level difference with respect to the upper surface of the first conductive portion, the level difference being formed of the insulating film pattern; a variable resistance film provided on a side surface of the level difference and having contact with the upper surface of the first conductive portion on the lower-end side of the side surface of the level difference; and a second conductive portion having contact with the variable resistance film on the upper-end side of the side surface of the level difference.
