A detection device and a rotation angle sensor include a case body and a cover member. A support portion in the case body is provided with fitting protuberances fitted in fitting holes of a printed board, on which a detection component is mounted, so as to position the printed board. Each protuberance has ribs protruding from an outer peripheral surface thereof. The ribs are elastically or plastically deformed by contact with an inner peripheral surface of the corresponding fitting hole of the board, and position the board along a support surface of the support portion. A projecting portion of the cover member is elastically or plastically deformed so as to urge the board toward the support surface of the support portion so that the board is clamped between the projecting portion and the support surface and is positioned in a direction perpendicular to the support surface of the support portion.
