PROBLEM TO BE SOLVED: To provide a phantom for calibration which performs quick and highly accurate temperature measurement, temperature change, and temperature control. SOLUTION: The phantom for calibration used for calibration of a component concentration measuring device for measuring the component concentration in a specimen by a photoacoustic method is equipped with a container 10 having an opening 11 for filling solution, wherein a low specific-heat high heat-conductivity part 17 having a smaller specific heat than alumina and a larger heat conductivity than alumina is formed on the whole part from an outer wall 13 to an inner wall 15; a reference material 20 mainly composed of water, with which the container 10 is filled; and a light transmission body 30 mounted so as to cover the opening 11 of the container 10, and formed of a material approximately transmissible by a near infrared ray.
