 wherein the first fabric is arranged on the part C and has a laminated structure of a first spunbonded non-woven fabric and a first melt-blown non-woven fabric, and 
 wherein the second fabric is arranged on the part A and the part B and has a laminated structure of a second spunbonded non-woven fabric and a second melt-blown non-woven fabric. 
   
     
     
         2 . The protective clothing of  claim 1 ,
 wherein a bulk density of the first melt-blown non-woven fabric is 0.05 g/cm 3  or more and 0.18 g/cm 3  or less,   wherein a thickness of the first melt-blown non-woven fabric is 70 μm or more and 200 μm or less,   wherein the first melt-blown non-woven fabric is a charged melt-blown non-woven fabric,   wherein the first spunbonded non-woven fabric and the first melt-blown non-woven fabric are adhered by a first adhesive, and a content of the first adhesive is 0.5 g/m 2  or more and 5.0 g/m 2  or less,   wherein a bulk density of the second melt-blown non-woven fabric is 0.20 g/cm 3  or more and 0.53 g/cm 3  or less,   wherein a thickness of the second melt-blown non-woven fabric is 30 μm or more and 120 μm or less,   wherein a bulk density of the second spunbonded non-woven fabric is 0.10 g/cm 3  or more and 0.15 g/cm 3  or less,   wherein a thickness of the second spunbonded non-woven fabric is 120 μm or more and 200 μm or less, and   wherein the second spunbonded non-woven fabric and the second melt-blown non-woven fabric are directly laminated or adhered by a second adhesive, and when the second adhesive is used, a content of the second adhesive is more than 0 g/m 2  and 0.4 g/m 2  or less.   
     
     
         3 . The protective clothing of  claim 2 ,
 wherein an average fiber diameter of fibers constituting the first melt-blown non-woven fabric is 3 μm or more and 15 μm or less.   
     
     
         4 . The protective clothing of  claim 1 ,
 wherein a QF value of the first fabric is 0.30 or more, and   wherein a QF value of the second fabric is 0.20 or less.   
     
     
         5 . The protective clothing of  claim 1 ,
