Abstract: An IC package includes a magnetic detection element, multiple lead lines electrically connected to the magnetic detection element, and multiple terminal lines weldable to the lead lines respectively. A first welding portion, in which a first lead line of the multiple lead lines is welded to a first terminal line of the multiple terminal lines, is not on vertical lines that pass through second welding portions in which the second lead lines of the multiple lead lines are welded to the second terminal lines of the multiple terminal lines respectively. The second lead lines are adjacent to the first lead line. The vertical lines are orthogonal to center axes of the second lead lines.

Abstract: A position detection device is configured to detect a position of a detection target. The position detection device includes: an IC package including a magnetic detection element configured to output a signal that depend on a direction or a strength of an ambient magnetic field, a sealing portion in which the magnetic detection element is sealed, and lead lines, which are projected from the sealing portion and are electrically connected to the magnetic detection elements; terminal lines electrically connectable to the lead lines respectively; and a lead guide placed along the lead lines to restrict positional deviation of the lead lines.

Abstract: A fuel property sensor includes an electrode portion, a first thermistor, a second thermistor, and a circuit portion. The electrode portion detects an electrostatic capacity varied according to an ethanol concentration in fuel as a fuel characteristic. The first thermistor is disposed in a flowing area inside the electrode portion, where the fuel flows through. The second thermistor is disposed in a non-flowing area where no fuel flows through. The circuit portion which computes the ethanol concentration based on the electrostatic capacity, a first detection value detected by the first thermistor, and a second detection value detected by the second thermistor. Thus, a fuel temperature can be properly detected, and a detection accuracy of the fuel characteristic can be improved.
