Abstract
A single-chamber-type temperature-sensor-provided crystal unit includes: a single chamber; and a quartz-crystal vibrating piece and a temperature sensor, provided in the single chamber. The quartz-crystal vibrating piece has a square planar shape. The quartz-crystal vibrating piece is secured in the single chamber at two securing portions via conductive members. The two securing portions are in proximities of both ends of a first side of the quartz-crystal vibrating piece. The temperature sensor has a rectangular parallelepiped shape. The temperature sensor is disposed such that a longitudinal surface of the temperature sensor is parallel to a line segment Y and the temperature sensor is close to a side of the two securing portions within the single chamber, when a line segment connecting the two securing portions is defined as the line segment Y.
