Abstract
A terminal for a piezoelectric device has a base contact portion and a bent contact portion which are preferably formed by folding a metallic material. Each contact portion has a protrusion disposed thereon. A lubricant is located between the base contact portion and the bent contact portion. The lubricant contains a hydrophilic group tending to form a hydrogen bond with a metal element and a lipophilic group extending in a straight chain from any such hydrogen bond and having a length at least several times that of the hydrophilic group. The lipophilic group has a molecular structure which urges away from the metallic surfaces of the contact portions.
