Abstract
A MEMS package has a MEMS chip, a package substrate which the MEMS chip is adhered, a chip cover which wraps the MEMS chip, and a pressure regulation film which is adhered to the front surface of the chip cover. The chip cover has a vent which is formed in a chip outside area, arranged outside than the MEMS chip, the pressure regulation film has a slit. The slit is arranged in the neighborhood of the vent and the vent is covered with the pressure regulation film.
