Abstract
To provide electronic circuit module capable of dissipating heat generated by electronic component while suppressing increase in thickness, and capable of improving identifiability and visibility of identification character and identification mark as compared with conventional technique. Electronic circuit module according to present disclosure includes board, plurality of electronic components mounted on upper surface of board; and sealing resin configured to cover electronic component. Sealing resin has lower surface in contact with upper surface of board, and upper surface positioned on opposite side from board with respect to electronic component to face in opposite direction from lower surface. Identification recess constituting at least one of identification character and identification mark when viewed from thickness direction of board is formed in upper surface of sealing resin. Identification recess is filled with filler made of material having higher thermal conductivity than material of sealing resin.
