Multiple trait prediction for a type of model with heterogeneous genetic and residual covariance structures.

An electricity storage device includes a casing, a terminal, and a current interruption device. The terminal includes a column part and a base part. A first sealing member having an insulating property including a first sealing part sealing between the terminal and a terminal wall is provided between the terminal and the terminal wall, and surrounding an entire periphery of the column part. A first insulating member having an insulating property is disposed within a first space provided between the terminal and the terminal wall on a casing inner side relative to the first sealing part, and surrounds the entire periphery of the column part. At least one of the first sealing member and the first insulating member is disposed in the first space from an end face of the first space on a casing outer side to an end face on the casing inner side thereof.
