Original Abstract Submitted
A switching element includes trenches extending in a first direction, inter-trench semiconductor layers, and connection regions arranged linearly at intervals along a second direction to form columns. The inter-trench semiconductor layers intersect the columns at intersection portions. The intersection portions include connection intersection portions including connection regions and non-connection intersection portions without the connection regions which are arranged in each of the columns in a pattern in which a portion where the connection intersection portion are arranged continuously and a portion where the non-connection intersection portions are arranged continuously are arranged alternately. A phase of the pattern is shifted in the second direction between the adjacent columns. A Chebyshev distance from each of the non-connection intersection portions to a closest one of the connection intersection portions is 1. A Chebyshev distance from each of the connection intersection portions to a closest one of the non-connection intersection portions is 1.
