Rotation detection device

A rotation detecting device, comprising:

• a member to be detected being configured to be fitted to a rotatable member, and being provided with a plurality of magnetic poles along a circumferential direction centered on a rotation axis of the rotatable member;
• and
• a sensor section being configured to be fitted to a fixed member that is not rotated by rotation of the rotatable member, and being arranged opposite the member to be detected,
• wherein the sensor section includes:
• two magnetic sensors, each including a plate shape detecting portion including a magnetic detection element, which is configured to detect a magnetic field produced from the member to be detected, and a connection terminal, which is extended out from the detecting portion, with the detecting portions of the two magnetic sensors being arranged in such a manner as to overlap each other in an opposite arrangement direction of the sensor section and the member to be detected;
• and
• a housing portion being made of a resin mold provided in such a manner as to cover the two magnetic sensors together, and including an opposite surface to the member to be detected,
• wherein the two magnetic sensors include a first magnetic sensor, which is arranged in a side of the sensor section close to the member to be detected, with the detecting portion of the first magnetic sensor being arranged in such a manner as to be inclined with respect to the opposite surface of the housing portion to the member to be detected,
• wherein the two magnetic sensors include a second magnetic sensor, which is arranged in a side of the sensor section away from the member to be detected, with the detecting portion of the second magnetic sensor being arranged in such a manner as to be inclined with respect to the detecting portion of the first magnetic sensor.
