 the second conductive member and an upper portion of the first conductive member. A resistivity of the first conductive member in the first direction is lower than a resistivity of the first conductive member in the stacking direction. A resistance value of the first conductive member in the stacking direction changes. A resistivity of the second conductive member in the second direction is lower than a resistivity of the second conductive member in the stacking direction. A resistance value of the second conductive member in the stacking direction changes.
