1. A magnetic sensor configured to output an electrical signal corresponding to a magnetic flux generated between a first magnetic circuit portion and a second magnetic circuit portion which are opposed to each other, the magnetic sensor comprising:
a magnetic sensing device that is configured to output the electrical signal which corresponds to the magnetic flux;
a sensor housing that includes:
a base body which holds the magnetic sensing device at one end portion of the base body, wherein the one end portion of the base body is configured to face the first magnetic circuit portion and the second magnetic circuit portion; and
a flange which is fixed to the base body and is configured to be placed in contact with a receiving wall that receives the first magnetic circuit portion and the second magnetic circuit portion; and
a pair of magnetic flux guide members that are respectively made of a soft magnetic material and are configured to guide the magnetic flux to the magnetic sensing device, wherein the pair of magnetic flux guide members are opposed to each other while the magnetic sensing device is interposed between the pair of magnetic flux guide members, wherein:
the flange is made of a material having a higher rigidity than the base body; and
the pair of magnetic flux guide members are held by the base body together with the magnetic sensing device.
