Abstract: A determination device includes a processor that is used for determining first paper having a surface on which an embossing process is performed and second paper having a surface on which the embossing process is not performed, a light source that irradiates a surface of paper with light, a light detector that receives the light transmitted through the paper and that detects a light transmittance, an ultrasonic transmitter that transmits an ultrasonic wave to the surface of the paper, and an ultrasonic receiver that receives the ultrasonic wave transmitted through the paper and that detects an ultrasonic transmittance, in which the processor is configured to: use an index that is stored in advance in a storage device and that indicates a correlation between the light transmittance and the ultrasonic transmittance in the second paper, and determine whether or not the paper is the first paper or the second paper according to whether or not the light transmittance and the ultrasonic transmittance, which are detected from the paper, are apart from the index by a predetermined threshold value or more.
