Failure predicting apparatus and machine learning device

A failure predicting apparatus for predicting a failure timing of a printed circuit board included in a management target device, the failure predicting apparatus comprising

• a machine learning device that learns the failure timing of the printed circuit board included in the management target device with respect to an operating state of the management target device, wherein
• the machine learning device includes
• a state observing unit that observes, as state variables indicating a current environmental state, operating state data indicating an operating state of the management target device and device configuration data indicating a device configuration of the management target device,
• a label data acquiring unit that acquires, as label data, maintenance history data indicating a maintenance history of the management target device, and
• a learning unit that, by using the state variables and the label data, learns the failure timing of the printed circuit board included in the management target device, the operating state data, and the device configuration data such that the failure timing is associated with the operating state data and the device configuration data.
