Abstract:
1. A method of making a physical quantity sensor comprising: preparing a casing with an insert-molded lead frame; applying a liquid or semi-solid vibration isolator to a supporting surface of a supporting portion of the casing; inserting a jig in an opening of the supporting portion of the casing so that an end surface of the jig is exposed to the supporting surface through the opening; attaching a first side of a sensor portion on the supporting surface through the applied vibration isolator, while limiting movement of the sensor portion toward the supporting surface by the end surface of the jig; and connecting a bonding wire between a second side of the sensor portion opposite to the first side and the lead frame, while limiting the movement of the sensor portion by the end surface of the jig.
