PROBLEM TO BE SOLVED: To substantially prevent a phenomenon that a flux is wetted up on a sample holding member to raise a disturbance in a wet waveform, and measure a sure wetting time. SOLUTION: This solderablity testing device is provided with (A) a sample holding means 20 provided with the sample holding member 23 for holding a sample 50, (B) an external force detecting means 10 for supporting the sample holding means 20, (C) a solder paste storage container 30 stored with a solder paste 31 containing the flux, and (D) a heating means 40 for heating the solder paste 31. A flux wetting preventing layer is formed at least on a surface of a sample holding portion 23A of the sample holding member 23.
