Position detection device

A position detection device, comprising:

• a magnetic detection element configured to detect a change in magnetic field;
• a wiring connected to the magnetic detection element;
• a first mold resin configured to mold the magnetic detection element and the wiring so that the wiring is exposed;
• a terminal connected to the wiring;
• and
• a second mold resin configured to mold the first mold resin and the terminal so that the first mold resin on which the magnetic detection element is located is exposed, wherein
• the second mold resin has a deformation suppressing portion configured to suppress the deformation of the first mold resin when deformed,
• the deformation suppressing portion is a groove portion extending in a longitudinal direction of the second mold resin while being recessed in a plate thickness direction of the second mold resin,
• a straight line passing through one end surface of the first mold resin and extending in the longitudinal direction of the second mold resin is referred to as a first straight line,
• a straight line passing through the other end surface of the first mold resin on the side opposite to the one end surface of the first mold resin and extending in the longitudinal direction of the second mold resin is referred to as a second straight line, and
• the deformation suppressing portion is formed between the first straight line and the second straight line.
