To provide a rotation detector which can improve detection sensitivity and prevents molding failure when a housing part is molded with a resin.SOLUTION: A sensor part 3 includes a plate-like detection part 300 including a magnetic detection element for detecting a magnetic field from a magnetic encoder 2 as a detected member, and a connection terminal 301 extended from the detection part 300, in which the detection part 300 is composed of two magnetic sensors arranged so as to overlap an opposite direction to the sensor part 3 and the detected member 2 and a resin mold provided so as to collectively cover the two magnetic sensors, has a housing part 31 having an opposite surface 314 opposite to the magnetic encoder 2, and in the two magnetic sensors, the detection part 300 of a first magnetic sensor 30a arranged on the side of the magnetic encoder 2 is arranged so as to be inclined to the opposite surface 314.SELECTED DRAWING: Figure 3 【課題】検出感度を向上でき、かつハウジング部の樹脂モールドの際に成形不良が発生しにくい回転検出装置を提供する。【解決手段】センサ部３は、被検出部材としての磁気エンコーダ２からの磁界を検出する磁気検出素子を含む板状の検出部３００、及び検出部３００から延出された接続端子３０１を有し、検出部３００がセンサ部３と被検出部材２との対向方向に重なるように配置されている２つの磁気センサと、２つの磁気センサを一括して被覆するように設けられた樹脂モールドからなり、磁気エンコーダ２と対向する対向面３１４を有するハウジング部３１と、を有し、２つの磁気センサのうち、磁気エンコーダ２側に配置されている第１磁気センサ３０ａの検出部３００が、対向面３１４に対して傾くように配置されている。【選択図】図３
