Abstract
A seal member that includes an insertion hole into which a connector terminal is insertable, wherein, when a direction in which the connector terminal is to be inserted into the insertion hole is defined as an insertion axis: an inner diameter of a cross-section of the insertion hole orthogonal to the insertion axis at a position at which the inner diameter is the smallest is denoted as a minimum hole diameter D, an outer length of a cross-section of the connector terminal orthogonal to the insertion axis at a position at which the outer length is the largest is denoted as a maximum terminal outer length L, and the minimum hole diameter D and the maximum terminal outer length L satisfy a relationship 2.1≤L/D≤4.2.
