Beschreibung
Zusammenfassung:	According to an embodiment, there is provided an apparatus (10) which quantitatively evaluates a braze bonding length. A radiation emission unit (12) emits radiation to each of a plurality of partial specimens which are obtained by cutting a specimen in a plane perpendicular to a braze bonding length direction. A light generator (16) generates light of an amount corresponding to an intensity of transmissive radiation. An imaging unit (18) photographs this light. A calculator (20) calculates a braze bonding length of each of the partial specimens, from a light amount obtained with respect to each of the partial specimens, based on a correlation between a braze bonding length and a light amount. The calculator (20) further calculates the braze bonding length of the specimen by totaling the braze bonding lengths of the respective partial specimens.
