Abstract

PURPOSE: To increase insulation resistance between strain gages and a cantilever by bonding an insulator having excellent insulating property to the cantilever as a bonding member.
CONSTITUTION: Chips 2A and 2B which are made of semiconductor material having piezo-electric function are attached to both sides of a cantilever 1 made of metallic materials by using metallic brazing materials or eutectic alloys. Strain gages 7A and 7B are formed on the surfaces of the chips 2A and 2B, a pn-junction is formed, and insulation is provided between both the strain gages 7A and 7B, and between the strain gages 7A and 7B and the cantilever 1. Since the insulation resistances of AC250V and of 1,000V in a special case are required between the strain gages 7A and 7B and the lever 1, metal reinforcing members 4A and 4B are bonded to the fixed portion of the lever 1 through bonding member 5A and 5B made of materials having excellent insulating property, and the insulation is secured by the bonding members 5A and 5B.
