Claim:
1. A strain sensor chip mounting structure comprising: an object to be measured including a surface to be measured; a strain sensor chip including a first main surface, a strain sensor element formed on the first main surface side, a second main surface positioned on an opposite side of the first main surface, and a side surface continued to the first main surface at a peripheral edge portion of the first main surface, the strain sensor chip being fixed to the object to be measured so that the surface to be measured and the second main surface face each other; and a metallic bonding material which is interposed between the surface to be measured and the second main surface of the strain sensor chip and which is bonded to the surface to be measured and the second main surface of the strain sensor chip, wherein the entire second main surface and the side surface of the strain sensor chip are covered with a successively-formed metallic film, and the metallic bonding material is bonded to the metallic film which is formed on the side surface of the strain sensor chip.
