PROBLEM TO BE SOLVED: To provide a method for analyzing an element in a sample with high measuring precision without using a high-pressure hydrogen gas as a calibration gas while ensuring reliability with respect to a measuring value, and an element analyzer. SOLUTION: In the element analyzer for measuring hydrogen or a plurality of elements containing hydrogen in the sample S subjected to melting treatment in an inert gas atmosphere, a hydrogen treatment part 5 having a hydrogen occluding alloy therein and capable of being heated and cooled is arranged to the sensitivity calibrating gas flow channel of a gas analyzer 2 for measuring hydrogen in a sample gas obtained by the melting treatment and hydrogen in the sample gas or the calibration gas is occluded as it keeps cooled. At the time of calibration of the gas analyzer 2, a specific carrier gas Ar is allowed to flow through the hydrogen treatment part 5 turned heated to calibrate the sensitivity of the gas analyzer 2.
