An energy-dispersive spectrometer (EDS) with a 64-pixel superconducting transition edge sensor (TES) microcalorimeter array mounted on a scanning transmission electron microscope has been developed. A 64-pixel array is read out by common bias SQUID. The crosstalk of a series connection of bias line is observed. We evaluated the effect of the crosstalk to energy resolution of TES microcalorimeter.
