An all-solid battery includes at least a unit cell including a positive electrode, a negative electrode, and an ion-conductive solid electrolyte layer interposed between the positive electrode and the negative electrode. The solid electrolyte layer includes an inorganic solid electrolyte, and a resistance R1 of the unit cell when the pressure applied in a thickness direction of the unit cell is 100 kPa is 90 Ωcmor less.

All-solid battery and method for producing the same

A method for producing a catalyst of the present invention is characterized by sequentially performing the steps of: (i) dipping an end face portion of a carrier structure having a catalytic component carried thereon in an aqueous metal salt solution at a concentration of 2.7 to 3.88 mol/L in terms of mole of the metal; (ii) drying the dipped end face portion; (iii) dipping the dried end face portion again in an aqueous metal salt solution whose metal species is the same as that in the aqueous metal salt solution at a concentration of 2.7 to 3.88 mol/L in terms of mole of the metal; and (iv) performing a calcination treatment to harden the catalytic end face.
