A sensor, which is small and suitable for reflow soldering by automatic cleaning and automatic mounting, can be manufactured in batch and has a switch function, and a manufacturing method of the sensor, and a portable telephone having the sensor built therein. The sensor is composed of a first board composed of a semiconductor by which a conducting part of the switch is formed, a second board composed of the semiconductor by which the conducting part of the switch is formed or an insulator by which a conducting part of the switch is formed, and a moving member having conductivity. The sensor having the switch function is provided by permitting either the first board or the second board to have a cavity-shaped part and by confining the moving member having conductivity by the first board and the second board. The method for manufacturing the sensor and the electronic device having the sensor built therein are also provided. ® KIPO & WIPO 2007
