PURPOSE:To obtain an adhesive for a piezoelectric vibration gyro capable of reducing variability of temperature characteristics of sensitivity change rate in a piezoelectric vibration gyro using a vibrating reed type vibrator and suppressing shift of sensitivity change rate to the-minus side, comprising a specific composition. CONSTITUTION:(A) 100 pts.wt. of a solid epoxy resin having 450-500 epoxy equivalent is blended with (B) 10-100 pts.wt. of a liquid epoxy resin having 166-215 epoxy equivalent (c) 0-100 pts.wt. of methyl cellosolve and (D) dicyandiamide as a curing agent in an equivalent blending ratio to epoxy group of 0.8-1.2 to give the objective adhesive. Bisphenol A type epoxy resin is preferable as the components A and B. The adhesive is preferably obtained by dissolving the component A in part of the component C, blending the solution with the component B to prepare a main agent, dissolving the component D in the rest of the component C to prepare a curing agent and finally uniformly mixing the main agent with the curing. |
