<p>A resolver/digital-converter having a self-fault-detection function without breaking normal operation is provided. The resolver (11) digital-converter, which has a normal operation function section, a temperature characteristic identification function section (12), and a first temperature characteristic correction function section of correcting estimated angle output from the normal operation function section based on a temperature characteristic identification value by the temperature characteristic identification function section, includes a holding function section (630) of holding the temperature characteristic identification value, and (2) a second temperature characteristic correction function section of correcting estimated angle output from the temperature characteristic identification function section based on the temperature characteristic identification value by the temperature characteristic identification function section, the value being held in the holding function section.
