An optical fingerprint imaging device, including a substrate, an imaging module, at least one light emitting element, a light shielding element, a case, and a pressing substrate, is provided. The light shielding element is disposed between the imaging module and the light emitting element. The optical fingerprint imaging device satisfies conditional expressions, h&#x2264;H&#x2264;h+(R/tan(&#x3b8;/2)) and Ravg&#x3c;S&#x3c;5Ravg, where h is a height from a field angle origin of the imaging module to the substrate, H is a height of the light shielding element at a measurement position, R is a distance from a center of the imaging module to the measurement position, &#x3b8; is an angle of a field angle of the imaging module, Ravg is an average value of distances from the center to measurement positions of the light shielding element, and S is a distance from the center to a center of the light emitting element.
