The current measuring device includes an upper solution chamber ( 3 ) and a lower solution chamber ( 8 ) whose bottom has a support layer ( 5 ) and measures a current flowing via an artificial lipid bilayer membrane ( 2 ) formed on a small hole ( 4 ) of the upper solution chamber ( 3 ), wherein the lower solution chamber ( 8 ) is provided below the upper solution chamber ( 3 ) by being surrounded with a bottom plate ( 6 ) and an interval keeping member ( 7 a). An internal pressure of the lower solution chamber ( 8 ) is dropped so that the artificial lipid bilayer membrane ( 2 ) formed on the small hole ( 4 ) swells to the side of the lower solution chamber ( 8 ) so as to be thinner, and the thinner artificial lipid bilayer membrane ( 2 ) is supported by the support layer.
