1. A resonator comprising:
a resonator device; a package to which the resonator device is attached; and a member which attaches the resonator device to the package, the resonator device including:
a base portion,a pair of vibrating arms which extend from one end side of the base portion in a plan view,a connection portion which is disposed on an other end side of the base portion in a plan view, anda linkage portion which is disposed between the base portion and the connection portion in a plan view and links between the base portion and the connection portion, each of the vibrating arms including:
a weight portion, andan arm which is disposed between the base portion and the weight portion in a plan view, and a width of the base portion along a direction intersecting with the extension direction is set as W1, a width of the linkage portion along the intersecting direction is set as W2, a Young's modulus of the member is set as E (GPa) and a relationship of −1.3≦log E<−0.7 is satisfied, and a relationship of the following formula:0.1≦W2W1≦0.7is satisfied.
