A molecular sensor of an embodiment includes a sensitive film including a plurality of metal organic framework particles, and a detector configured to be capable of measuring a change in physical quantity due to adsorption of a target molecule to the sensitive film. Pores are present between the plurality of metal organic framework particles, and the pores are any of mesopores of 2 nm or more and 50 nm or less, micropores smaller than the mesopores, and macropores larger than the mesopores. A sum of areas of the micropores is defined as Smi, a sum of areas of the mesopores is defined as Sme, a sum of areas of the macropores is defined as Sma, and an area of an entire image analysis area is defined as Stotal, in an image analysis area by two-dimensional image analysis on a cross section of the sensitive film in a thickness direction. Pore distribution satisfies 0.35≤Sme/(Smi+Sme+Sma), 0.01≤Smi+Sme+Sma)/Stotal≤0.5.
