SENSOR ELEMENT AND ANGULAR VELOCITY SENSOR

In a piezoelectric body of a sensor element, two first arms extend alongside each other from a base part to a +y side. Two second arms extend alongside each other from the base part to a -y side. A holding part extends between the two second arms from the base part to the -y side and extends out beyond front ends of the two second arms to the -y side. A mounting part on which a plurality of element terminals are located is connected to an end part on the -y side. The holding part includes a main portion and a connection portion. Where the length in an x-direction is the width, the main portion extends from a position between the front ends of the two second arms to a side where the base part is located, while maintaining a width not less than a width of a portion located between the front ends of the two second arms. The connection portion which is connected to the main portion and the base part and is broader in width than the main portion.
