Position detection device

A position detection device configured to detect a position of a detection target, comprising:

• an IC package including
• a magnetic detection element configured to output a signal that depends on a direction or a strength of an ambient magnetic field,
• a sealing portion in which the magnetic detection element is sealed, and
• a plurality of lead lines projected from the sealing portion and electrically connected to the magnetic detection element;
• and
• a plurality of terminal lines weldable to the plurality of lead lines respectively, wherein
• a first welding portion, in which a first lead line of the plurality of lead lines is welded to a first terminal line of the plurality of terminal lines, is present in a position not on vertical lines that pass through second welding portions in which second lead lines of the plurality of lead lines are welded to second terminal lines of the plurality of terminal lines respectively,
• the second lead lines are adjacent to the first lead line, and
• the vertical lines are orthogonal to center axes of the second lead lines respectively.
