A calcium silicate board containing calcium silicate that includes a tobermorite crystal, wherein the calcium silicate board includes the tobermorite crystal such that the sum of products of the strength It (unit: cps) and half width Wh (unit: °) of three or more peak tops selected from plane indices (002), (004), (220), (408) and (620) derived from the tobermorite crystal in an XRD pattern of the calcium silicate is 60% or more with respect to the sum of products of the strength It0 (unit: cps) and half width Wh0 (unit: °) of the peak top in an XRD pattern of a reference tobermorite crystal, and wherein the calcium silicate board comprises pores such that the sum Vpa of the pore volume measured by mercury porosimetry is 0.97 to 4.6 cm3/g, the sum Vp1 (unit: cm3/g) of the log differential pore volume of pores having a pore diameter of 5.0 μm or less is 90% or more with respect to the sum Vpa' (unit: cm3/g) of the log differential pore volume of the total pores, and the sum Vp2 (unit: cm3/g) of the log differe
