Patent ID: 8309385

Claim:
A method of manufacturing an inertial sensor, in which a sensor device in which is packaged a detection element that detects an amount of a physical quantity, and a lead frame that includes a plurality of lead terminals electrically connected to the sensor device are mold packaged in resin; an upper mold being provided that has a first concave portion for forming a cavity, and a second concave portion for forming a coupling path at both sides of the first concave portion; a lower mold being provided that has a third concave portion for forming the cavity, and a fourth concave portion for forming the coupling path at both sides of the third concave portion; the method comprising: a step of seating the sensor device in the cavity that is provided by placing together the first concave portion and the third concave portion; a step of seating the lead frame in the coupling path that is provided by placing together the second concave portion and the fourth concave portion; and a step of injecting the resin into the cavity from the coupling path, and molding the resin; a concave bottom portion of at least one of the top mold or the bottom mold being inclined with respect to a line parallel to the lead frame.
