A video image decoding device (1) is equipped with a TT information decoder (14) that, in the case where encoded data includes merge/skip information that merges or skips presence information indicating whether or not frequency-domain transform coefficients are included in the quantized transform coefficients, does not decode the presence information, and a TT information inference unit (33) that, in the case where the encoded data includes merge/skip information that merges or skips the presence information, infers the presence information. The TT information decoder (14) uses presence information inferred by the TT information inference unit (33) to decode the encoded and quantized transform coefficients.
