An electric apparatus, comprising: a resin member having an attachment surface facing a substrate; a wall section surrounding a specific area of the attachment surface; at least one terminal protruding from the specific area to an outer side of the resin member; and a projection section provided between the wall section and a base of the at least one terminal, the projection section having a tip end exposed from a seal member covering the base of the at least one terminal in a state where the seal member is in the specific area, the tip end being provided apart from the at least one terminal and the wall section, characterized in that: i) the specific area has a slope section formed such that a distance between an opening surface of the wall section and the specific area facing the opening surface increases as a distance from the wall section to the at least one terminal decreases, such that when a seal liquid is supplied to the slope section, the seal liquid is configured to spread along the slope of the slope section toward the terminal, or ii) the electric apparatus further comprises a guide section provided in the specific area and extending in a direction from the wall section toward the at least one terminal, wherein the guide section is a projection or a groove, such that when a seal liquid supplied to the specific area comes into contact with the guide section, the seal liquid is configured to flow along the guide section toward the terminal, or iii) a surface roughness of the specific area facing an opening surface of the wall section is greater than a surface roughness of the projection section. a resin member having an attachment surface facing a substrate; a wall section surrounding a specific area of the attachment surface; at least one terminal protruding from the specific area to an outer side of the resin member; and a projection section provided between the wall section and a base of the at least one terminal, the projection section having a tip end exposed from a seal member covering the base of the at least one terminal in a state where the seal member is in the specific area, the tip end being provided apart from the at least one terminal and the wall section, characterized in that: i) the specific area has a slope section formed such that a distance between an opening surface of the wall section and the specific area facing the opening surface increases as a distance from the wall section to the at least one terminal decreases, such that when a seal liquid is supplied to the slope section, the seal liquid is configured to spread along the slope of the slope section toward the terminal, or ii) the electric apparatus further comprises a guide section provided in the specific area and extending in a direction from the wall section toward the at least one terminal, wherein the guide section is a projection or a groove, such that when a seal liquid supplied to the specific area comes into contact with the guide section, the seal liquid is configured to flow along the guide section toward the terminal, or iii) a surface roughness of the specific area facing an opening surface of the wall section is greater than a surface roughness of the projection section. i) the specific area has a slope section formed such that a distance between an opening surface of the wall section and the specific area facing the opening surface increases as a distance from the wall section to the at least one terminal decreases, such that when a seal liquid is supplied to the slope section, the seal liquid is configured to spread along the slope of the slope section toward the terminal, or ii) the electric apparatus further comprises a guide section provided in the specific area and extending in a direction from the wall section toward the at least one terminal, wherein the guide section is a projection or a groove, such that when a seal liquid supplied to the specific area comes into contact with the guide section, the seal liquid is configured to flow along the guide section toward the terminal, or iii) a surface roughness of the specific area facing an opening surface of the wall section is greater than a surface roughness of the projection section.
