A physical amount detecting device includes: one pair of driving vibration arms are bending-vibrated in a direction of a X-axis, one pair of first detection vibration arms and one pair of second detection vibration arms are vibrated in a direction of a Y axis, depending on a Coriolis force that is generated in accordance with rotational angular velocity of X-axis rotation, the one pair of the first detection vibration arms are bending-vibrated with a first phase in a direction of a Z axis in addition to vibration in the direction of the Y axis, and the one pair of the second detection vibration arms are bending-vibrated with a second phase, which is a phase opposite to the first phase, in the direction of the Z axis in addition to vibration in the direction of the Y axis.
