The first straight line region has a steeper inclined angle with respect to the first imaginary straight line than the second straight line region. Positions of both ends of the first straight line region and positions of both ends of the second straight line region are aligned in a direction corresponding to a width direction of a magnetic tape. A plurality of gap patterns deviate from each other by a predetermined interval in a direction corresponding to a longitudinal direction of the magnetic tape, between the gap patterns adjacent to each other along the direction corresponding to the width direction of the magnetic tape. A substrate is inclined with respect to the first imaginary straight line.
