The description relates to activity cards. Therefore, a multilayer capacitor is obtained that not only can realize both downsizing and higher capacity, but also has reliability not lowered with time. 2, and the intrinsic coercive force of the bonded magnet at the room temperature is in the range of 320-720 kAm. The transient response data and the steady-state response data are jointly inverted to identify a subsurface feature, such as resistivity. The cradle is rotatable between a first attitude and a second attitude around a rotation axis line perpendicularly intersecting the first face.
