CIRCUIT MODULE AND METHOD OF MANUFACTURING CIRCUIT MODULE

摘要

PROBLEM TO BE SOLVED: To highly precisely control a tilt angle of an acceleration sensor to a circuit substrate, to allow the acceleration sensor to highly precisely detect an acceleration, and to reduce a tilt angle error by suppressing influence due to temperature change in mounting an electronic device with the need of highly precisely maintaining an azimuth. SOLUTION: The circuit module includes a circuit substrate 10 which is fixed by two or more fixing points and forms a component loading part and a circuit pattern on a surface and a component chip 20 which is loaded on the component loading part of the circuit substrate. The component chip 20 is mounted near an inner edge of a cantilever 22 which is formed by two slits 21 formed from positions with a predetermined space at one side of the circuit substrate and extends from near the center of the circuit substrate onto the one side.
