Abstract: A magnetic sensor has a first tube-shaped bias magnet and a first magnetic sensor element. The first tube-shaped bias magnet has a bottom face, a top face facing the bottom face, and an outer side surface and an inner side surface both located between the bottom face and the top face, and includes an N pole formed by magnetizing one of the bottom face and the top face and an S pole formed by magnetizing a remaining one of the bottom face and the top face. The first magnetic sensor element is located in an inner space surrounded by a plane including the bottom face, a plane including the top face, and the inner side surface. The magnetic sensor can detect intensity of an external magnetic field with high accuracy.
