Patent ID: 7518202

Claim:
A semiconductor mechanical quantity measuring apparatus for detecting the strain of an object of measurement by coupling a first main surface of a strain-detecting semiconductor element to the object, wherein the strain-detecting semiconductor element is supported on a wiring board through a first elastic member on a second main surface of the strain-detecting semiconductor element to thereby form a triple layered structure including the semiconductor element, the first elastic member and the wiring board stacked on one another with the first elastic member sandwiched between the semiconductor element and the wiring board, and wherein at least a part of the end portions of the joint between the strain-detecting semiconductor element and the first elastic member is reinforced by resin, and the first elastic member is lower in elastic modulus than the resin, and wherein a bending rigidity of the triple layered structure is greater than a bending rigidity of the semiconductor element to thereby decrease the likelihood of breakage of the semiconductor element due to bending.
