Abstract: A physical quantity sensor includes a sensor portion, a casing, and a vibration isolator. The casing includes a supporting portion with a supporting surface that is located to face an end surface of the sensor portion. The vibration isolator is located between the end surface of the sensor portion and the supporting surface of the casing to join the sensor portion to the casing. The vibration isolator reduces a relative vibration between the sensor portion and the casing.

Abstract: A rotation angle sensor includes a sensor integrated circuit attached to an attachment member. The attachment member includes a connecting terminal protruding upward from an attachment surface and a guide protruding upward from the attachment surface and positions, together with the connecting terminal, the sensor integrated circuit at an attachment position. The sensor integrated circuit includes a lead frame on which an electronic circuit is mounted and an exterior covering the electronic circuit. The lead frame includes a lead and an extending portion located in an outer periphery of the exterior. At least one of the lead and the extending portion has an elastic structure. The sensor integrated circuit is attached to the attachment member by an elastic force of the elastic structure that biases the extending portion against the guide and that joins the lead to the connecting terminal.

Abstract: A position detecting device includes an IC package, a first terminal line, a ground terminal line, a power supply terminal line, a second terminal line, a bypass terminal line, motor terminal lines, and a connector portion. A bypass terminal line is positioned on an opposite side of the ground terminal line across the first terminal line or the second terminal line and is connected to a bypass portion of the ground terminal line which connects to the ground connection portion. In the connector portion, the motor terminal line, the bypass terminal line, the second terminal line, the power supply terminal line, and the first terminal line are placed in this order.
