An organic transistor comprising a semiconductor active layer containing a compound represented by the following Formula (2) and has a molecular weight of equal to or less than 3,000;

• in Formula (2),
• each X′ independently represents an oxygen atom, a sulfur atom, or a selenium atom;
• each Z′ is independently selected from NR7, an oxygen atom, a sulfur atom, and a selenium atom;
• a ring containing Z′ is an aromatic heterocycle;
• R1 and the aromatic heterocycle containing Z′ are optionally bonded to each other through the following group A of divalent linking groups;
• R3 and a benzene ring are optionally bonded to each other through the following group A of divalent linking groups;
• the group A of divalent linking groups represents any one of divalent linking groups —O—, —S—, —NR8—, —CO—, —SO—, and —SO2— or represents a divalent linking group in which two or more of these divalent linking groups are bonded to each other;
• R1, R7, and R8 each independently represent a hydrogen atom, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, or a heteroaryl group and optionally further have a substituent, and two or more R1s are the same as or different from each other;
• each R3 independently represents an alkyl group, an alkenyl group, an alkynyl group, an aryl group, or a heteroaryl group and optionally further have a substituent, and in a case where m is 2, R3s are the same as or different from each other;
• each m is independently an integer of 0 to 2;
• here, a case where both Z′ are NR7 is excluded;
• in a case where X′, Z′, and R1 in Formula (2) are a sulfur atom, a sulfur atom, and an alkyl group respectively, R1 and the aromatic heterocycle containing Z′ are bonded to each other through the group A of divalent linking groups;
• and
• a case where R1 is a hydrogen atom and each m is 0 is excluded.
